### The Nature of Sleep

It lies in the nature of current scientific observations that the phenomena we want to dedicate today’s lecture to are basically not much talked about by current natural science. Yet every human being should feel that sleep is something how is placed among the phenomena of our life as if life’s greatest riddles are presented to us through it. Surely people always must have felt the mysteriousness and significance of sleep when they spoke of sleep as the ‘brother of death.’ Today, we have to limit ourselves to speaking of sleep as such, because the coming lectures will repeatedly lead us back to the contemplation of death in many ways.

All that man in a direct sense counts as belonging to his soul experiences, all imaginations that from morning to evening surge up and down, all emotions and feelings which constitute man’s soul drama, all pain and suffering, and the will impulses as well—all of it sinks down, as it were, into an indeterminate darkness when the human being falls asleep.

Some philosophers might doubt themselves, so to speak, when they talk about the nature of the soul, about the nature of the spirit that reveals itself in human nature. Yet, they have to admit that even if it had been firmly nailed down by definitions and ideas and showed itself to be well researched, it basically seems to disappear into nothing within the course of each day.

If we look at the manifestations of our soul life in the way one usually does so scientifically and also amateurishly, then we basically must say that these are extinguished during the state of sleep; they are gone. For someone who only wants to observe the physical expressions of the soul, the human being becomes on deeper reflection, so to say, all the more a riddle. Because the actual bodily functions, the bodily activities, continue during sleep. Only what we usually call the ‘soul’ discontinues.

The question then arises as to whether one is speaking about bodily and soul matters in the right sense when one includes what appears to be extinguished on falling asleep, when actually the soul aspect is included to the full extent. Or, if already the ordinary observation of life, apart from Spiritual Science or anthroposophical observations, could show us that the soul is active and proves to be effective even when it is enveloped by sleep. However, if one wants to gain some clarity about those concepts, or one could say, if one wants to observe the manifestations of life in this field in the right sense, one must place exact terms before one’s soul.

By way of introduction, I would like to mention in advance that on this topic as well, Spiritual Science or Anthroposophy is not in a position to make generalisations of the kind that people love to make today. If today we talk about the nature of sleep, then we will only talk about the nature of human sleep. In the last lecture, with regard to other fields, we have touched on this many times—Spiritual Science knows very well that which outwardly manifests itself in the same way, as this or that other appearance by different beings, can have quite different causes in the respective beings. We have indicated that this applies to death, to the whole spiritual life and to the formation of the spiritual life of animals and human beings. Today, it would go too far to also talk about the sleep of animals. Therefore, we want to say in advance that all we talk about today applies only to the sleep of human beings.

Through our consciousness, we can speak about soul manifestations within ourselves—anyone can feel this—because we are conscious of what we imagine, want, and feel. Now the question must arise—and this is extremely important particularly for today’s observations—whether we may readily combine the definition of consciousness as we use it for the ordinary consciousness of a human being in the present with the concept of the soul or the spirit in a human being? First, to express myself more clearly about these concepts, I like to draw a comparison. A man might walk around in a room and cannot see his own face in any spot in that room. The only place he can see his face is where he can look into a mirror. His own face appears as an image in front of him. Isn’t there an enormous difference for man whether he just walks around in a room and lives within himself or whether he sees what he expresses of this living also in a mirror image? It could probably be so with human consciousness in a somewhat extended way. The human being could, so to speak, experience his soul life—and he would only become knowledgeable or conscious of this soul-life itself, the way he lives it, when it confronts him like a mirror. This could very well be. Thus, we could say, for example, that it is quite possible that the human soul life continues regardless of whether the human being is awake or asleep. But that the waking state consists of the fact that the human being perceives his soul life through a mirroring, let’s say first of all, through a mirroring within his physicality and that he cannot perceive it in the state of sleep because it cannot be mirrored in his physical body.

Although we have not yet proven anything with this, at least we would have gained two concepts. We could differentiate between the soul life as such and becoming conscious of the soul life. We can think that for our consciousness, for our knowledge of the soul life, as we currently stand in our everyday human life, everything depends on us receiving the mirror image of our soul life through our physicality because if we do not receive this, we cannot know anything about it. We would then be wholly in a sleeping state. Now that we have gained these concepts, let us try to place the phenomena of waking and sleeping life a little before our soul.

Someone who is really able to observe life, will feel very clearly, and one would like to say, will ‘behold’ how the moment of falling asleep truly proceeds. He can perceive how the imaginations, the feelings weaken in their brightness, diminish in their intensity. But this is not the most essential. When a human being is awake, he lives in such a way that he creates order through his self-conscious Ego in his whole imaginative life, whereby he summarises, as it were, all ideas with his Ego. For at the moment when we in our waking life would not summarise all our ideas with our Ego, we would not be able to lead a normal soul life. We would have one group of ideas that we would relate to ourselves and call our concepts and another group we would look at as something foreign, like an external world. Only people who experience a split in their Ego, which for people today would be a state of sickness, could have such a tearing apart of their imaginative lives into different areas. For a normal person it is essential that all his ideas are in perspective related to a single point: the self-conscious Ego.

The moment we fall asleep, we feel distinctly that, at first, the Ego will be, so to speak, overwhelmed by imaginations despite these growing dimmer. The ideas assert their independence; they live an independent life. Single clouds of ideas, as it were, form within the horizon of consciousness, and the Ego loses itself in imaginations. Then man feels how the sense perceptions like seeing and hearing and so on become blunter and blunter, and finally, he feels how the will impulses are paralysed. Now, we must point out something clearly observed by just a few people. The human being feels furthermore, as he sees things with defined borders in his daily life, that at the moment of falling asleep, something asserts itself like a feeling of being locked up in a vague fog, which occasionally makes itself felt as cooling, or with other sensations in certain parts of the body: on the hands, on the joints, on the temples, on the spine etc. These are feelings that someone falling asleep can very well observe. They are, one would like to say, the kind of trivial experiences that one can have every evening when falling asleep if one wants to.

Better experiences are had by people who, through a finer developed soul life, more precisely observe the moment of falling asleep. They can then feel something like an awakening despite falling asleep. What I am about to tell you now, can be told by anyone who has acquired certain methods of really observing these things, because it is a common human phenomenon. The moment people feel like an awakening when they are slipping into sleep can really be described as follows: something like an expanding conscience, like morality, wakes up in the soul. This is indeed the case. This is particularly shown when people observe their soul concerning what they have experienced the previous day and with which they are satisfied in their conscience. In the moment of moral awakening, they feel this especially clearly. At the same time, this feeling is quite the opposite of the feeling during the day. While the feeling during the day shows itself by things approaching us, one who falls asleep feels as if his soul is pouring itself out over a world that is now awakening. This mainly includes a relaxation, a pouring out of feeling over that which the soul, through itself can experience in relation to its moral inner being as if through an expanding conscience. Then it is a moment of inner bliss, which appears to be much longer for the one falling asleep, when it is about dwelling on things with which the soul can agree. There is often a deep conflict when the soul has to reproach itself. In short, the moral human being who, during the day, is repressed through the strong sensory impressions, relaxes and feels himself very distinctly when falling asleep.

Everyone who has acquired a particular method, or maybe even only a feeling concerning such observations, knows that at this moment a certain longing awakens, which we could describe like this: One really wants this moment to extend into the indefinite, that it would never end. But then comes something like a ‘jolt’, a kind of inner movement. For most people, this is very difficult to describe. Of course, Spiritual Science can describe this inner movement quite precisely. It is, as it were, like a demand that the soul makes on itself: You must now relax even further; you must pour yourself out further. But by making this demand of itself, the soul loses itself for the moral life in its surroundings. This is like throwing a small drop of colour into water and dissolving it: the colour can still be seen at first. But once the drop distributes itself throughout the water, it pales more and more and finally, the colour display as such stops. So it is when the soul is just beginning to swell and live in its moral mirror image where it can still feel itself, but the feeling stops once the jolt, the inner movement, occurs, as the drop of colour loses itself in the water.

This is not a theory; it can be observed and is accessible to everyone, just like a natural scientific observation is exactly accessible to everyone. If we thus observe the process of falling asleep, we can certainly say that the human being intercepts, as it were, something when falling asleep that, afterwards, he somehow can no longer be conscious of. If I may be allowed to use both of my earlier constructed ideas—the human being has, as it were, a moment of parting from the mirror of the body in which the manifestations of life appear to him as mirror images and because he has no other means to mirror what otherwise is mirrored by the body, the possibility to perceive himself, ceases.

Again, it is possible to perceive in a certain sense the day’s happenings—if one does not want to be altogether stubborn and obstinate regarding what relates to the soul and the effect of what moves into an vague darkness. I have already pointed out in another context that someone forced to memorise this or that, i.e., learn things by heart, can do this much more easily if he sleeps on it more often, and that depriving oneself of sleep is the greatest enemy of memorisation. The possibility and the ability to memorise more easily even returns once we have slept on an issue and not want to learn something by heart in one go. This is also the case with other activities of the soul. However, we could convince ourselves very easily that it would be impossible to learn anything at all, to acquire anything when the soul is involved, if it weren’t for the inclusion of sleep states among our life states. The natural conclusion that has to be drawn from such phenomena is that our soul needs to withdraw from time to time from our physical body, in order to gain strength from an area that is not within our body, because the respective strengths within the body are being worn out. We must imagine that when we wake up in the morning from sleep, that from the state in which we were then, we have brought along strength to develop abilities, that we could not develop if we were constantly shackled to our bodies. This is how the effect of sleep shows itself in our ordinary nature, when one wants to think straight and not be obstinate.

What shows itself in general when one pauses in ordinary life, and for which one needs some good will to hold one’s life phenomena together, is shown very clearly and precisely when man goes through developments that are able to lead him to a real beholding of the spiritual life. Here I would like to elaborate on what occurs when a human being has developed the forces that lie dormant within his soul in order to reach a state in which he can neither perceive with the senses nor comprehend with the mind. This will be followed up in more detail in the lecture *How does one Attain Knowledge of the Spiritual World*,[^1] where the methods will be quite comprehensively covered. Right now though, we will highlight some of the experiences that a person, truly practising such exercises is able to have that endow his soul, as it were, with spiritual eyes and spiritual ears, and through which he can look into the spiritual world, which is not an object of speculation, but for someone who perceives with his senses, it is just as much an object as colours and forms, warmth and coldness, and sounds. How to attain true clairvoyance has already come to light in previous lectures. This spiritual development, these exercises, actually consist of a person bringing out of himself something that he has within himself, gains other organs of perception, jolting upwards, as it were, over the soul, as it is in its ordinary state, and thus perceives a world that is always around him but which cannot be perceived in the normal state. When a person undergoes such exercises, the first thing that changes is his sleep life. Anyone, who has done their own real spiritual research knows this. I would now like to talk about the very first stage of change in the sleep life of a person who is actually clairvoyant and engaged in spiritual research. The first beginnings of this possibility of spiritual research do not make the person appear very different from the normal ordinary state of consciousness because a person who performs these exercises, as we shall discuss later, will at first sleep like any other human being and is just as unconscious as anyone else. But the moment of waking up will show something very special to the one who has performed spiritual exercises. I will now describe to you some very concrete phenomena that are based on facts.

Let’s assume that a person who is practising these exercises is thinking very hard about something that another person could also be thinking about. He tries, maybe because he has a very difficult problem in front of him, to exert all his mental power to get to the bottom of it.

Perhaps he’ll be like a schoolboy: his mental power just isn’t sufficient to solve the problem. This could definitely happen. If he has now already obtained through his exercises more possibilities to experience the inner states of the soul in connection with the physical state, he will certainly feel something quite peculiar when he finds himself incapable to do something. Unlike usual, he perceives a resistance in his physical organs, for example in his brain. He properly senses that the brain puts up resistance against him, just as we feel resistance when we try to drive in a nail with a hammer that is too heavy. The brain then begins to gain a reality. The way man normally uses his brain, he would not feel it as if he were using an instrument, as is the case with a hammer, for example. A spiritual researcher feels his brain, he feels himself independent in relation to his thinking. That is an experience. But if he can’t solve a task, he feels that he is no longer able to carry out certain activities that he must perform when thinking. He feels very clearly that he is losing power over the instrument. This fact can be experienced very precisely.

If the spiritual researcher sleeps on the problem and then awakens, it will often happen that he feels up to the task without any further ado. But at the same time he also feels precisely that prior to waking up he has done something, that he has worked on something. He feels that he had been able to set something within him in motion during his sleep, that he had caused an activity. During the waking state he was forced to use his brain. He knows that. He can do nothing but use his brain when he is awake. But he was no longer able to use it properly, because—as I have described—it resisted him. During sleep, he feels, he is not dependent on using his brain. He was able to create a degree of flexibility without using the brain that was too tired or otherwise too heavily occupied. Now he feels something very peculiar: he perceives the activity that he has performed during sleep, albeit not directly. The Lord gives to his own, but not in their sleep. The spiritual researcher is not saved from having to solve his problem now in the waking state. It may come easily to him, but normally it is not so, and particularly not with things that simply must be solved by the brain.

Hence, the human being feels something that he has not known before in the sensory world—he senses his own activity, which presents itself to him in vivid pictures, in strange pictures that are in motion. It is just as if the thoughts he needs were living beings who would enter into all kinds of relationships with each other. Thus he senses his own, let’s call it, ‘mental activity’ that he undertook during sleep, like a series of pictures. This feeling is difficult to describe, as one is stuck in it in a quite peculiar way and has to tell oneself, ‘This is you yourself!’ But, on the other hand, one can distinguish this feeling very clearly from oneself, in the same way as one is able to distinguish a physical movement one makes from oneself. Thus one has pictures, imaginations of an activity performed before waking up. And now one can notice, if one has learned to watch oneself, that these pictures of an activity that was performed prior to waking up, connect themselves with our brain and turn it into a more flexible, more useful instrument, so that one will be able to complete something, which one could not do before because of a resistance, for example, to think certain thoughts. These are subtle things, but without them one won’t really get behind the secret of sleep. Thus, one feels that one has not performed an activity as in the awake state, but one that served the restoration of certain things in the brain which were worn out. The instrument has been restored in a way that was not possible before. One feels like a master builder of his own instruments.

The feeling during such an activity is significantly different from that during a daytime activity. The feeling one has about the day activities is comparable to copying something from a template or a model. There I am forced to follow the picture in front of me with every stroke or dot of colour. In regard to the things that appear as pictures at the moment of waking and that are, as it were, an illustration of an activity during sleep, one has the feeling of inventing the strokes, of creating the figures out of oneself, without being tied to a model. With such an occurrence one will have, as it were, intercepted what the soul did prior to waking up: one has intercepted the activity of brain regeneration. Because sooner or later one realises that what feels like a kind of coating the brain organs with what one remembers as figures is nothing other than a restoration of what has been damaged in the course of the day. One really has the feeling of being a master builder working on oneself.

Basically the difference between a spiritual researcher who perceives such things and an ordinary person is only that a spiritual researcher just perceives these things, whereas an ordinary person cannot pay attention to them and does not perceive them. The same activity that the spiritual researcher undertakes is performed by every human being, but the normal person doesn’t catch the moment when the organs are restored by the activity that takes place during sleep.

Let’s take such an experience and compare it to what was previously said about an increase in bluntness and dullness, and a reduction in brightness of the daily imaginative life at the moment of falling asleep. This latter phenomenon can only be viewed in the right light if one either frees oneself from today’s highly suggestive concepts of the world view that believes itself to be firmly based on natural science, or by actually accepting the available results of contemporary natural research. For example, in brain research, and according to the results of natural research, people who think more precisely can do nothing but acknowledge the independence of the spiritual from the physical. And it is very interesting that recently a popular book was published in which basically everything that has to do with spiritual life and the sources of spiritual life was presented wrongly and completely without any insight. But in this book, *The Brain and the Human Being*, by William Hanna Thomson,[^2] a lot of smart things are said. It deals in particular with modern brain research and with many other things that are presented—for example, as I also have more often pointed out—with symptoms of fatigue, which are quite instructive. But I have already explained that muscles and nerves cannot get tired in any other way than through conscious activity. As long as our muscles only serve an organic activity they cannot become tired. It would be bad if, for example, the heart muscle and other muscles needed rest. We only become fatigued when we perform an activity that is not innate to the organism—such as an activity that belongs to the conscious life of the soul. Thus one has to say; if the soul life was born out of the human being like the heart activity, then the immense difference between fatigue and non-fatigue could not be explained. The author of the book therefore feels compelled to acknowledge that the soul relates to the physical no differently than a rider relates to his horse, i.e., that it is completely independent from the physical. This is an enormous concession from a person who thinks like a natural scientist. One could get very strange feelings if, forced by contemporary natural research, one has to confess to oneself that the relationship between the soul life and the body life must be imagined as being roughly the same as that of a rider to a horse. That is, according to the image that people had of a centaur in earlier times, when they still looked deeper into the spiritual realm.

It is not apparent that the author of the book would have thought of this, but again this thought comes to mind from the natural scientific conception, and one gets the feeling that such ideas stem from times when a certain clairvoyance still existed for many people. Today, however, certain imaginations about centaurs seem to be more compatible with what a gentleman once told me: He said:

> ‘The Greeks watched the Scythes, who came from the North, and other rider clans, perhaps when they emerged from a fog. They could not distinguish the shapes clearly, and so they thought that these had grown out of the horse.’ A materialist might be satisfied with such an explanation. But it is just contemporary natural scientific research that pushes for an acknowledgment of the independence of the soul from the physical.

One thing we can hereby definitely notice, and we can follow such things best if we recall certain occurrences before our soul that are not commonplace, but still exist and cannot be denied. The spiritual researcher knows how that common man in the country, at the hour of his death, suddenly began to speak in Latin, a language he had never really used and which one could prove he had only heard once in Church when he was a little boy. This is not a fable, but a reality. Of course he did not understand anything of it, when he had heard or recited it. And yet it is true. From this, the idea should be formed in every human being that what affects us in our environment contains something in addition to what we absorb into our normal consciousness. Because what we absorb into our ordinary consciousness is often dependent on our education, on what we comprehend and the like. But not only what we can comprehend unites itself with us, but we have in us the possibility to absorb endlessly more than what we take up consciously. We can even observe in every human being how at certain times he has ideas, that were not strongly noticed at the time he experienced them here or there, so that he may not remember them at all. But through certain things they re-appear, and may even place themselves into the centre of his soul life. We really have to acknowledge that what constitutes the extent of our soul life is endlessly more than what we can receive and embrace with our day consciousness. This is extraordinarily important. Because in this way our attention is steered towards something inside of us that can really only make a slight impression on our corporeality because it has hardly been noticed, and then again it lives on in us. In this way, we are pointed to the foundations of our soul life, which should actually exist for every reasonable person. Every rational person should tell himself that, what is in the world around him for his consciousness while he is consciously looking at the world, is basically dependent on the organisation of his sensory organs and on what he can understand. And no one is entitled to want to limit reality by what they can perceive. It would be completely illogical to want to deny the spiritual researcher that behind the physical world a spiritual world exists, simply for the reason that man is only allowed to speak about what he sees and hears and what he can think about, and he is never allowed to judge what he cannot perceive. Because the world of reality is not the world of the perceptible. The world of the perceptible is limited by the sensory organs. For this reason one should never —in the Kantian sense—speak of the limits of knowledge; or about what a human being may or may not know, but only about that what he has before of him in accordance with his organs of perception.

Considering this, one must say to oneself: Behind the colourful carpet of the sensory world, behind that which the warmth sense perceives as warmth or cold and so on, lies an infinite reality. Should therefore only what we perceive, or only the reality we perceive exert an influence on us? If we think that we are only shown a part or a section of the entire reality through our perception, then it is only logically tenable that there lies an infinite reality behind what can be given to us through our perception. However, this is also real for us, as we have been placed in it, so that what surges and lives outside and influences us, lives on for us. But what is our actual waking life like during the day? There really is no other way than to imagine the waking day life in this way, and to say; ‘We open our senses, our capacity to realise something immense and confront this immensity. Because each person has particular eyes, particular ears, and a certain sense of warmth, and so on, we are placing a particular section of reality in front of us. Anything else we reject, almost, as it were, fend it off, exclude it from us. So what does our conscious activity consist of? It consists of a defence against, or an exclusion of something different. And by straining our sensory organs, we are holding back something that we have not perceived. What we perceive is the remainder, are the remains of what is spreading itself around us, and what we, for the most part reject. In this way, we feel actively placed in this world, feel connected with it. Likewise, we defend ourselves through our sensory activity against a multitude of impressions, because, figuratively speaking, we are not able to bear the entire immeasurable infinity and take in only a section of it. If we think like this, then we must imagine quite different relationships between our whole organism, our entire bodily nature and between the external world, than those which we can perceive or comprehend with our intellect. Then it will not seem so unusual to think that the relationships, which we have with the outside world, live in us and that also the invisible, super-sensible or extra-sensible is active within us—and that the extra-sensible by being active in us, uses our senses to fabricate a section out of the entire immeasurable reality. Then our relationship to reality is completely different from how we are able to perceive it through our senses. Then there lies something of relationships with the outside world in our soul that does not exhaust itself through sensory perception, that eludes our waking daytime consciousness. Then it is with us as if we are stepping in front of a mirror with our inner being and have to say to ourselves:

> ‘Basically you are something completely different. The mirror only shows you the forms, maybe also the colours; but within you you are thinking. You are feeling within you. All of this the mirror cannot show you. It only shows you what is dependent on its laws. As a soul facing its organism, you are something completely different from what your senses show you; they limit you to what is according to their laws. When you face the world, as with a mirror—you are actually facing a world that is only made possible by the organisation of your senses!’

If you think this idea through to the end, then you will not be surprised to find that basically all life of our awake day consciousness depends very much on the organisation of our sensory organs and on our brain, just as what we see in a mirror depends on the quality of the mirror. Anyone who looks into a garden mirror and sees a caricature of their face looking towards them, will happily agree that the picture in the mirror is not dependent on them, but on the mirror. In the same way, what we perceive depends on the set-up of our mirroring apparatus, and our soul activity is limited, as it were, reflected back into itself by mirroring itself in our body life. Then it is no longer astonishing that the detail—and this can also be physiologically proven—is dependent on the physical body, whereby this or that happens one way or another in our consciousness. Because everything that the soul does in order for something to become conscious, to become knowledge for us, depends on the organisation of our body. Observation shows us that the concepts that we initially only constructed, actually correspond to the facts. The only difference is that our corporeality is a living mirror. We let the mirror in which we look be as it is. However, there is one way in which we can influence the reflection: if we breathe on the mirror, then it can no longer reflect properly. But the reflection in our physicality, which experiences the activity of our soul, is connected with the fact that when we reflect ourselves in our corporeality, the reflection itself is an activity, a process within our bodily nature, and that which appears as a reflection, we place as an activity before ourselves.

Thus the bodily life actually presents itself as if, in a certain sense, we would write down what we think and then would have the characters in front of us. This is how we write the activity of our soul into our physicality. What an anatomist can verify are only the characters, the external apparatus, because we do not completely observe our soul life if we only observe it within our physical life. We only observe it completely, if we do this independently from our physical life. This, however, can only be done by the spiritual researcher who observes the soul life as it shows itself mirrored into the waking day life at the moment of awakening. It shows that the soul life is like an architect, who builds something during the night, and acts as a dismantler during the day.

Now we have the soul life in the waking state and in the state of sleep before us. In the state of sleep we have to imagine it as independent from body life, like a rider is independent from the horse. But just like the rider uses the horse and uses up its strength, the soul consumes the activity of the body so that chemical processes run like letters of the soul’s life. With this we reach a point where the physical life, as it is limited in the senses, in the brain, is so diminished by us that we have exhausted it for the time being. Then we must begin the other activity, initiate the reverse process and again build up what has declined. This is the life during sleep—so that we, starting from the soul, perform two opposite activities on our body. So, during the awake state we have around us our world of flowing and ebbing concepts, joy and sorrow, feelings and so on. But while we have them in front of us, we wear out our physical life, we basically destroy it constantly. During sleep, we are the architects, we can restore what we have destroyed during our waking life.

So what does a spiritual researcher perceive? He perceives the architectural activity of rebuilding in curious pictures like a circular movement twisting around itself: a real process, that is the reverse of normal awake day life. It is really no fantasy when one speaks about recognising in these self-entwining movements the mysterious activity that the soul performs during sleep, which consists of reconstituting what we have destroyed during our day life—hence the recuperation through and necessity of the sleep life. So why is the sleep life such that it doesn’t enter into our consciousness? Yes, and why is it that we become conscious of our waking life? The reason for this is that for the processes we perform in our waking day life, we have got something like mirror images. However, when we are performing the other activity of rebuilding what has been worn out, we have nothing wherein this could be reflected. We are lacking a mirror for this. Only a spiritual researcher is able to show the underlying reasons for this. From a certain point onwards, the spiritual researcher experiences not only the soul activity, as I have described it, like a dream memory from sleep, but as if he was not dependent on the instrument of the body, so that he then can perceive an activity which only happens in the spirit. He can then tell himself: ‘Now you are not thinking with your brain, but you are now thinking in a completely different manner; now you are thinking in pictures, independent of your brain.’

The spiritual researcher can only experience something like what has been described earlier, when he experiences that everything that envelops him as something nebulous when he falls asleep does not disappear. Instead, if he is able to limit and withdraw his inner activity, then the mist that is perceptible at his temples, at his joints, at his spine, becomes something that reflects what he is doing—similar to the reflection of what we experience during our physical life.

The whole difference between true clairvoyance and ordinary waking day life consciousness is that the waking day life requires a different mirror for the soul activity to come to consciousness and uses our bodily nature for this purpose. However, the activity of the clairvoyant, when it radiates as an activity of the soul, is so strong that the emitted ray will be withdrawn into itself. In this way, as it were, a mirroring on one’s own inner experience, on a spirit organism, takes place. Basically, our soul is within this spirit organism during the night, even if we are not spiritual researchers. It pours itself into it. And we will not be able to cope with our whole sleep life, when it is not clear to us that indeed our physical processes—all that anatomy, physiology is able to research—cannot bring about anything but a reflection of our soul processes; and that these soul processes always, from falling asleep until waking up, live a spiritual existence. If we think differently we won’t be able to cope at all. We must therefore speak, as it were, of a secret soul life that cannot enter at all into the consciousness conveyed through our body. Thus, when one notices in a person that ideas appear in his consciousness that he has ignored for a long time, one has to say: There is something else in a human being, apart from the conceptions of his conscious soul life, to which he has paid attention when he took them in.

I have already suggested once, that it is child’s play to refute things that are a reality for a spiritual researcher. And yet they are true. Spiritual research has to say that in regard to the human being we have to deal with a human physical body that we can see with eyes, grasp with hands, and that is also known to anatomy and physiology. In addition, we have an inner member of the human being, the astral body, the carrier of everything that the human being consciously absorbs, what he really experiences during the day life, so that he can receive it reflected by the body. Between the astral body and the physical body lies the carrier of ideas that remain ignored for years, and are then brought up into the astral body to be realised. In short, between the astral body, the carrier of consciousness, and the physical body, the etheric body of man is active. This etheric body is not only the carrier of conceptions that have gone unnoticed, but in general the builder of the entire physical body.

What actually happens during sleep? The astral body, the carrier of consciousness, lifts itself together with the Ego out of the physical body and the etheric body, so that a split in the human nature occurs. During day life when man is awake, the astral body and the Ego are within the physical body and the etheric body. And the processes of the physical body work like mirroring processes, through which all that happens in the astral body comes to consciousness. Consciousness is a reflection of the experiences through the physical body, and we should not confuse consciousness with the experiences themselves. When, during sleep, the astral body of an ordinary human being leaves, it is at first not able to perceive anything in the world of the astral. The human being is unconscious there.

What ability does the spiritual researcher now acquire when things during sleep become conscious to him, even though he does not rely on his brain? He attains the ability to perceive and to mirror his soul activity in something that for him weaves and lives between things, so that during the awake day consciousness this something can be perceived in the same way as his own etheric body. The human etheric body is woven from that through which the clairvoyant person perceives; so that for a clairvoyant person the outer world becomes reflective, just as for the soul life of a normal person the physical body becomes reflective.

Now there are intermediate states between waking and sleeping. One such intermediate state is the dream. With regard to its origin, spiritual research shows that indeed dreaming is based on something similar to clairvoyance, whereby the latter is something trained, while dreaming is always imaginary. When a person leaves with the astral body, he loses the ability to obtain a reflection of his soul life through the physical body. However, under certain abnormal circumstances, which occur for everyone, he can obtain the capability to receive his soul experiences reflected through the etheric body. Indeed we must consider not only the physical body as a mirroring device, but also the etheric body. As long as the outer world makes an impression on us, it is indeed the physical body which acts as mirroring device. However, if we become still within ourselves and digest the impressions the outer world has made on us, then we work within ourselves and yet our thoughts are still real. We live our thoughts, and also feel that we are dependent on something more subtle than our physical body, namely on the etheric body. Then the etheric body is that what reflects itself in us in solitary pondering, which is not initially based on external impressions. But we are within our etheric body during our awake day consciousness; we perceive what is mirrored, but we do not perceive directly the activity of the astral body. In the intermediate state between waking and sleeping, we do not have the ability to receive external sensory impressions. But because we can still receive something that is connected to our etheric body in some way, the etheric body can mirror what we experience in our soul with our astral body. This then are the dreams that show irregularity because the human being is in a completely unusual situation during this process.

If we contemplate this, then much in our dream-world will become clear that would otherwise remain mysterious about it. We must therefore imagine the foundations of the soul life as being closely connected with the dream life. While the physical body is the mirror of the soul life and our daily interests have an impact on this, we are often connected in the remotest way through the etheric body to experiences, which we have long since left behind, and of which we become only dimly aware because the day life has a strong impact on us. Thus they remain something extremely unknown to us. However, if we are examine dreams that are based on really good observation, many peculiar things can be shown to us. For example, a good composer experiences an image, where a somewhat diabolical figure plays a sonata to him. He wakes up and is able to write down the sonata. Something became active in him that has worked like something foreign. And this was possible, because there was something in him for which the composer’s soul was ready, but which could not become effective during the awake day life, because physical life was only an obstruction and not suited as a mirror. Here we can see that the bodily life is an inhibitor and in this lies its significance. In our daily life we are only able to experience that for which the bodily life, figuratively speaking, is ‘oiled like a machine.’

The physical life is always a hindrance to us, but we manage to use it to a certain extent. After all, one does need ‘inhibitions’ everywhere. When a locomotive rides over the tracks, it is the hampering, the friction, through which it can drive, because the wheels could not turn without friction. In reality, our bodily processes are what confronts our soul life in a hampering way, and these frictional processes are at the same time mirroring processes. When we are ready in our soul for something but have not yet managed to oil our machine well, then the awake day life is a good ‘brake shoe’. But when we leave our physical body, then our etheric body is able to bring what lives in our soul life to expression—and this will appear to us as something quite foreign as it is of a more subtle nature. Then, once it is strong enough, it forces itself into the dream life, as was the case with the composer. This has less to do with the daily interests than with the hidden interests, that lie more remote in the subtle foundations. For example, in the following—note, that I am just telling you something that has actually been observed—A woman dreams, and although she has children whom she loves very much, and a husband, who loves her extraordinarily, she experiences with great joy that she gets engaged for a second time and all related events she goes through. What does she dream? She dreams experiences that are very far from her current life, that she has once gone through but cannot recognise, because the normal interests of the day are only connected with the physical body. And, what has continued to live on in her etheric body will now, perhaps because a joyful emotion has triggered the dream, be mirrored by the etheric body through another event.

A man dreams that he goes through childhood experiences, and these childhood experiences are wonderfully mirrored. One of these, especially important to him because it went close to his heart, causes him to wake up. At first the dream is very dear to him, but soon he falls asleep again and dreams on. A whole sum of unpleasant experiences now pass through his soul, and a particularly painful event wakes him up. All of this is extremely far from his present experiences. He gets up, and because he feels very shaken by the dream, walks around in the room for a while, but then he lies down again and now he has dream experiences, which he has not yet had. All events that he went through get muddled up, and he now experiences something completely new. The whole turns into a poem, which he can even write down and set to music afterwards. That is a very real fact. Now it shouldn’t be too difficult, with the concepts we have already gained, to imagine what has happened there. For a spiritual researcher it is thus; at a very specific moment in his life the man suffered a kind of break in his development—he had to give up something that lay in his soul. But even if he had to give it up, it did not disappear from his etheric body as a result of that. It was just that his ordinary interests were so strong that they pushed it back. And, where it was strong enough through inner elasticity, it forced itself out through the dream, because there the human being is freed from the hindrances of the awake day life. This means, that the respective man was truly once very close to reach what was expressed in the poem; but then it had been deadened.

Thus we can see illustrated in our dreams the independence of our soul life from our outer bodily life. We must realise that this is proof that the idea of the mirroring of the soul life in the physical life is entirely justified. In particular, the circumstance that the interests in which we are involved do not engrave themselves in a straight line in our direct experience, shows us that apart from the life, as it is lived on a daily basis, there is another life running alongside, that I have called, for a more conscious, finer observation, a kind of awakening. In it lives everything that for our spiritual life is already abstract, immaterial like our conscience that is independent of physical life—everyone can feel this. Yet during our day life this other life turns out to be very limited by our daily interests. During sleep, our soul also reveals itself as being completely filled with its moral quality. There is a real living into the spiritual, what we can describe as a jolt, as an inner movement. What we call Spiritual Science research will result in something for us through which we can consciously settle into the world that the normal human being unconsciously settles into every time he falls asleep.

People must gradually familiarise themselves with the fact that the world is far wider than what we can grasp with our senses and follow with our intellect; and that the sleep life is an area that we need because just our noblest organs, which serve our imaginative life, are worn out by our daily life. During sleep we restore them, so that they can face the world strong and vigorously and are able to mirror our soul life for us in the waking day life. Everything that is characteristic of the soul life could become clear to us through this. Who wouldn’t know that one feels wearied and tired after a good, deep sleep? People often complain about this; but it is not a symptom of an illness at all and is actually quite understandable. After all, the complete recovery through sleep only occurs an hour or an hour and a half later. Why? Because we have worked well on our organs, so that they are not only able to cope for a few more hours but for the whole day. And immediately after waking up we are not yet ready to use them, we first have to “grind them in.” Only after a while we can use them well. One should speak about a particular type of weariness in a certain way, saying that one could be happy that one can settle back into the reconditioned organs in an hour and a half. Because from sleep comes to us what we need—the architectural forces for the organs that have been worn out and used up during the day.

So we may now say that our soul life is a life of independence, a life of which we have something like a reflection through our consciousness during our waking day life. Consciousness is a reflection of the interactions of the soul with its environment. During the waking day life we are lost to our surroundings, to something foreign, are devoted to something that is not ourselves. But during sleep—and this is the nature of sleep—we withdraw from all outer activity to work on ourselves. The comparison is apt; the ship which has served shipping while it was at sea will be rebuilt and repaired when it arrives in port.

Someone who believes that during sleep nothing happens to us, could also think, that nothing needs to be done to the ship when it returns to port from a voyage. But when the ship sails again, he will see what happens, if it has not been repaired. This is how it would be if our soul did not work on us during sleep. We are brought back to ourselves when we sleep, while during the day life we are lost to the outside world. A normal human being is just not able to perceive what the soul is doing during sleep in the same way as he perceives the outside world during the day.

In the lecture *How to attain Knowledge of the Higher World?* we will see that also in the spirit a mirror image can be attained as a realisation, through which man can then come to perception in the higher worlds. All this illustrates that the soul, just when it is not conscious of itself and knows nothing of its own activity, but is busy with itself, works on itself, and independently of the physicality, obtains those forces which serve precisely to build up the body.

Thus we may summarise what we have said, and characterise the nature of the soul with words that from the knowledge of the nature of sleep can build a kind of foundation for many things in Spiritual Science:

> The soul itself restores  
> Enveloped still in sleep  
> Flees into spirit worlds  
> When senses constrictions  
> Oppress it![^3]
