### VII. Structure and Breakdown in the Human Organism — The Significance of Secretions

Good morning, gentlemen! Perhaps one or the other of you has thought of something else you would like to ask? Or anything else about what we discussed the other day?

Mr. Müller asks if Dr. Steiner would like to say something about a question he asked the other day: There are quacks who can diagnose people's illnesses from their urine.

Dr. Steiner: Yes, you asked that recently. I just overlooked the question, or I didn't have time to answer it.

Mr. Müller continues as the person asking the question: In the Basel area, there is a man who has

his practice, urine tests, and the remedies he has prescribed have achieved good results. What do you think of that?

Dr. Steiner: Well, regarding the question about urine testing, I have the following to say. Urine testing is not limited to quacks and the like, but it also plays a major role in medicine today, which is recognized as scientific. However, there is a big difference between the way in which today's physicians and the people you are actually talking about – and you were basically talking about non-medical practitioners – treat things, and that is based on the following. Urinalysis has always played an extremely important role in all disease investigations since ancient times. However, you have to bear the following in mind. If you go back to the old medicine that existed until the 18th century – because medicine was only reformed in the 18th century in Italy in the direction of materialism – you will find that both the recognition of diseases and healing were based on completely different principles. Today, this old medicine is completely despised by science. To a certain extent, this is justified, but it is not entirely justified. And one must be aware of the difference between the old medicine and the newer medicine in order to understand what it actually means today. The old medicine knew very well that man is not just this physical body that you see with your eyes and touch with your hands, but is also a supersensible being that permeates the body, as we have always emphasized.

You will find the differences between this old medicine and the newer medicine if you go back very far in human life, namely if you go back to the time before birth. I do not mean the spiritual before birth, but the physical, the body of the human being in the womb. Today, medicine and science in general see the essential thing about a human being as it develops in the womb, the essential thing is how the egg gradually builds up. At first, we are only dealing with the egg that has been fertilized. This is therefore a small cell, only visible under the microscope. This cell then multiplies and takes on a kind of cup shape. And in the third week, this cup shape bulges out on one side. Then, in the sixth or seventh week, the human being becomes similar to a small fish. On one side, the head then develops (see drawing), and the first nerve cords form here. And so it continues. And in this way, observing formation after formation, today science is trying to get closer to understanding the origin of man and also of animals.

But apart from what is present in this way, there is also a thick liquid around the human being in the womb. This thick liquid is present in this way (it is drawn), and only then is the uterus all around it. This thick liquid, with all kinds of thick inclusions, then flows out at birth as the so-called afterbirth. This is considered to be a waste product, something that has no significance, because everything that occurs in a living being today, that is, that occurs in such a way that it comes out, is considered a waste product.

But that is not the case. Here, in the way the cell multiplies and the physical human body forms, the external natural force is at work inside, while in the surrounding fluid, which is then expelled as the afterbirth, the spiritual-soul element is at work. This spiritual-soul substance is first in the vicinity of the small human body; only later does it move into the human body. And one must actually look for the spirit in what is later rejected as the afterbirth. This is, of course, very surprising, but it is extremely important.

Today, there is so much denial of the spiritual that a friend of mine has set himself the task of examining this afterbirth, as it gradually releases the spirit to the actual embryo, the actual physical. One could examine this quite well scientifically; but that fails only because, where one gets human germs - it is not the case in very many cases - the fact that the mother dies or has to be operated on, the present-day natural scientists immediately take away everything that is around, and one does not get a human germ to examine in order to find out. So even the way things are treated today is a hindrance to real science. This materialistic way of thinking, I might say, begins with the examination of the origin of man.

Now you know that a person also secretes while they are alive. The secretions are not particularly popular in the external world, because they do not smell good. Almost all secretions do not smell good. Today, however, all secretions are considered, and quite rightly so, to be something that simply has to be secreted, washed away, and so on.

So the secretions in humans are, first of all, what you have mentioned: urine, perspiration, right, and then there are the coarse secretions, the feces and a few others. After all, what you cut from the nails is also a secretion of the human body. It is just a solid secretion. But some things that are also secretions are not recognized as secretions, but in reality they are secretions.

You see, the eye is often thought of as the noblest organ in the human being. Well, you just have to consider how easily an eye can be removed. It lies almost completely isolated in the eye socket. And what is in the eye as fluid – I have explained this to you – is also a secretion. And that there are secretions in the various organs of hearing, in the ear, that the secretion plays a role there, you can already see from the formation of earwax, which is the outermost secretion. So we are dealing with secretions everywhere in the human being; on the one hand the human being is built up, but on the other hand he dissolves, he secretes.

Now, what follows from this? I told you something the other day that might be instructive for you in this regard. I said: People see the nerves, the whole brain, as something that is just such an organ as the other organs, like the liver or spleen. But that is not true, gentlemen. The brain is a secretion. The whole brain, I told you, is a secretion! And if you want to compare the brain to something, then you should not compare it to the intestines, but to what is inside the intestines. So if you have a piece of intestine, there is the intestinal wall, and there is the intestinal contents (see drawing p. 159, bottom). The thing is that the intestinal wall is so corrugated. In the brain, in the nerve, the wall is missing; it is also there, but it is transparent, it is not visible, and only the contents are there (see drawing, above). You can quite rightly say: What is our brain actually filled with? It is filled with a very special kind of intestinal content! And if you call the intestinal content dirt, you can say that the brain is dirt. That is absolutely scientifically correct. For the activity of thinking does not consist in an activity of the brain, but the activity of thinking consists in the brain being separated out by thinking. The more you go from bottom to top in man, the more man is separation.

Now I have spoken to you about the sensual and the supersensible man, about the man you see and the man who is also in you, whom you do not see. That which you see in a person is what is continually being built up, what comes from what forms the physical human body. That is where he gets the arm stump (see drawing on p. 156), and the leg stump. But the supersensible, the astral body and the ego, are there to separate, they are constantly separating. Only the physical body and the etheric body build up. The astral body and the ego break down again.

When you build a house, you try to build it as quickly as possible and live in it for as long as possible. Little by little, nature also breaks it down. Otherwise, you would still have to see the houses that stood in ancient India today. But you will find few of our houses that stood here three hundred years ago. In the human being, building up and breaking down happens simultaneously. First, there is building up: We eat, absorb things; they come to the liver, where they are transformed. Then the breakdown begins again, the sorting out. And in this building and breaking down, the whole activity of the human being actually consists. If we only built up, we would be dull and stupid. We would be nothing but stupid fellows. We would not even be stupid fellows, but we would be completely spiritless plants if we only built. The fact that we break down, that we, for example, continually excrete in the brain, that we therefore have excretory organs, glands, is what it is that we are not stupid guys, but that we are clever people, with differences of course. But the spiritual is based on breaking down, not on building up. And that is why the secretions are of particular importance.

You see, the thing is this: the same activity that takes place when the afterbirth is secreted takes place during every decomposition. Whenever more and more is destroyed around the structure of the human being, then the spirit is at work. And when the spirit can then work in the human body itself, when the human being is born, then the afterbirth is no longer needed; then it is simply expelled. But it is expelled throughout life. It is expelled in the more or less solid-soft intestinal secretions, it is expelled in the urine, it is expelled in sweat, for example. You can observe the significance of sweat as a secretion when you have a real anxiety dream. Just observe it once when you have a real anxiety dream. If, for example, you dream that someone is chasing you with the intention of killing you or at least beating you up, you run away from him, you run in your dream, run, run, run; you wake up quickly, but not without being completely bathed in sweat. This activity, which is so intensified that you have such frightening images, takes place in the form of sweating attacks. And these sweats are the physical accompaniment of what the anxiety dream is. Or think of a person with a serious lung disease who is not in the last stage, but whose lungs are not in order. The lungs cannot breathe well, causing the lungs to compress: he suffers greatly from anxiety dreams. But he also always sweats when he sleeps. So you have the connection between the perspiration and these mental activities, images that come in dreams. Yes, then, gentlemen, the etheric body is active because the anxiety dream actually arises only at the moment of waking up. You only think that dreaming lasted almost the whole night. The whole dream takes place at the moment of waking up.

It can be proven that dreams play out at the moment of waking up. I once told you a characteristic dream, when many of you were not yet here, from which you can see how, when you wake up, you first have the whole dream flashing through your mind. A student is standing at the door of the lecture hall. Another student comes up to him and jostles him. Now, being jostled is a terrible insult among students! It can only end in a duel; there's no other way. So now, immediately, the moment the other student bumps into him, one of them looks for a second; the other student also has to look for a second – this is a long story that the student dreams – the whole thing is agreed, the negotiations for the seconds, everything; apparently it takes an awfully long time. He dreams of how they go out into the forest, how they line up, how the distance is determined, how they pace off how far away they are. The pistols are loaded – he dreams all this –; how they are then raised, the first shot is fired, and he wakes up! He quickly realizes that, because he has become restless in his sleep, he has tipped over the chair; but it falls while he is waking up. So the chair falling over made the whole dream; at that moment the whole dream shot through his mind. The dream only expands inwardly to the length. In reality, one actually dreams in the moment of waking up. And that is why it is also the case that such sick people have the frightening dreams when they wake up; they sleep, wake up, and in doing so, they start to sweat. That is the etheric body at work. When we wake up early of our own accord, we go back inside with our ego and astral body, which have left the physical body during the night, and that is why we break out in sweat. So when we sweat, it is the etheric body that mainly brings about the fact that we are spiritual beings, because stones and plants do not dream, and therefore are not spiritual beings.

But then there is the secretion of urine. You see, this is not as noticeable as it is with sweat because sweat can do nothing but come out, and then it covers the skin. But if the skin had small sacs where the sweat is secreted inside, and if there were a fine skin to cover it, you would not notice it at all. It could be that you have small sacs inside the skin. The sweat goes in there, and at certain times – you could have fine muscles – you press the skin and the sweat could run off. Just as the sweat is secreted through the etheric body, so is the urine secreted through the astral body. But you don't realize that, for example, when you have more vivid feelings, more urine is secreted than when you have weak feelings, because the urine does not pour out immediately. You see, it's like this: If a person is filled with enthusiasm and remains so, regardless of whether it finds expression in external deeds or whether he is contemplating something, and if he did not have a urinary bladder, then he would have to pass urine continuously, especially when filled with enthusiasm. It would be a very bad arrangement. A person could not go to a museum, because when he sees the pictures there and becomes excited, there would have to be toilets nearby! It just so happens that human nature provides for this secretion. It accumulates in the urinary bladder and can be drained at certain times. But urine is secreted primarily by the astral body, and this fills the human being everywhere; urine comes from everywhere, collects in the kidneys and then goes into the urinary bladder.

And the secretions of the intestines are particularly under the influence of the ego – in animals they are also under the influence of the astral body, but in humans they are under the influence of the ego. And not only the intestines are activated for secretion, but the whole human being is activated. In the whole human being, secretion is constantly taking place. The intestines are only the drainage system. So you can say that it is precisely in the secretion that you can see that the etheric body is active in sweat, the astral body is active in urine, and the ego is active in the secretion of feces.

If you consider this, you will not think of the secretions as something so unimportant. Because let us assume that a person has normal urine. Yes, then the astral body in the person is also active in a normal way. But whether a person is healthy or sick depends on how the astral body is active. Everything in health and illness basically depends on how the astral body is active.

For example, when we eat eggs and the eggs are to be digested, the egg must first go into the mouth, then into the stomach; then it goes into the intestines, and there, as I once said, it is completely destroyed as an egg. The egg white is destroyed. But then, on the way into the liver, the destroyed egg white is rebuilt, and human egg white is formed from animal and vegetable egg white on the way from the intestines to the liver. The human egg white then enters the blood.

If you look at the human organism, here is the diaphragm (see drawing), here is the liver, and here is the heart; they are only separated by the diaphragm. What comes from the intestines into the liver is transformed from animal and vegetable proteins – I will color this yellow – into human proteins (a darker yellow). This is held together in the liver and then passes over into the heart.

The thing is this: when we eat protein, our astral body has to work to properly transform animal and vegetable protein into human protein. If the astral body is lazy, it cannot work properly, and the animal protein is not converted into human protein in the liver, but goes directly into the kidneys and is secreted in the urine. If you now examine the urine – which is what modern scientific medicine does – you will find protein in the urine.

Or imagine, gentlemen, you are eating potatoes. The potato is usually already converted in the mouth, because starch is an important food in general, it is not just there to starch shirts. The potato consists almost entirely of starch. On the way from the mouth to the stomach and into the intestines, the potato is now gradually converted into sugar. The potato starch first becomes dextrin and then sugar. Potatoes are only bad in the mouth; in the intestines they are extremely sweet because they are converted into sugar there. But when the potato starch has been converted into sugar in the intestines, and when the liver has converted potato sugar or any other sugar into human sugar, then it delivers this inner sugar to the entire body, which becomes warmer as a result, which has its inner warmth as a result. But for that to happen, the astral body has to work properly again. If it does not work properly, then the proper transformation into human sugar does not take place, but the animal and especially the vegetable sugar goes directly to the kidneys. The sugar is excreted, and the person becomes diabetic. You can see from the sugar content of the urine that the person is ill.

All of this is something that modern medicine also does and considers to be extremely important. That is the first thing that is done today: the urine is examined for protein and sugar. This immediately provides a clue as to whether the person may have this or that disease.

Or take the following: if we want to have a healthy head, which, after all, is not something entirely unimportant for the physical human being here on earth – people want to have a healthy head because they believe that the head organ in the human being; so they want to have a healthy head. If we want to have a healthy head, then we have to bring up a substance that is constantly being produced in us, namely clover acid, through the chest into the head. A healthy head must have a certain amount of clover acid. We produce the clover acid ourselves, as we also produce the alcohol we need. But for this, the head must work in the right way again, so that the clover acid, oxalic acid, is produced. If it does not work properly and it stays down, we get a head that is anemic, and the clover acid is passed into the urine and goes away.

From this you can see, gentlemen, that even today the most important diseases can be identified by means of the most ordinary chemical examination of urine. But this chemistry that we have today was not available in the past. And there was medicine even then!

Now the matter is this: suppose a person has a fever; I will take a drastic case. What does it mean when a person has a fever? It does not mean that his astral body has become weak and listless, sluggish, but rather that it is in a state of excessive activity, so that it affects the I. Then the I is as if whipped when the astral body is in excessive activity. But the I causes the blood to circulate. And an excessively active astral body, which wants to enter the organs everywhere and cannot, and therefore seethes within itself like a storm-lashed sea, produces fever within itself. Now the person has a fever from his whipped astral body. What will be the further consequence? The blood is rushed through the body too quickly. The Blur is not properly transformed. The blood does not have time to form the organs, but goes as blood from the heart to the kidneys and from there into the urine, and we get a urine that is very dark in color. Those who know how to judge the dark color of urine know that, under all circumstances, whether it is a little darker or very dark, the fever is flooding the human organism.

Suppose the astral body becomes very sluggish, it will no longer work properly. The blood passes very slowly through the body, the pulse becomes barely noticeable. You can feel it at the pulse, how the blood passes slowly everywhere. Everything in the body comes together. The body experiences pain in all sorts of places; the urine turns light yellow or even white. Now, between the urine being dark and the urine being white, there are all kinds of shades, color nuances. If you focus on these color nuances and take the urine and look at it through the light, you can see a wide range of things from the colors of the urine.

The blood is constantly trying to replace what is leaving the organs. As a result, the blood has a constant tendency to solidify. If the blood rushes through the organs too quickly, it cannot give anything to the organs. But it wants to solidify. When it comes out of the kidneys as urine, the urine becomes flaky in such blood. If you look through it again, you will see flaky urine. If the astral body is sluggish and the pulse weak, then you don't have cloudy urine, but rather urine that is almost as clear as water, pure urine.

So not only from the color, but also from this cloudiness or purity of the urine, one can conclude a lot. If the urine, when you look through it, looks like a stormy summer's day, with dark clouds and everything in it showing, where everything is bubbling in the urine, so if it is like a stormy summer's day, then the person has something that causes a strong fever. And if you can judge what is going on, you can draw conclusions about the illness. If the urine, when examined, looks delightfully clear like a bright summer's day when the sun illuminates everything, one can conclude that the person is ill on the other side, that he has a very slight tendency towards all kinds of perishing organs; one organ becomes inactive, another becomes inactive, and so on.

So you see, the thing is this: if you have specialized in the secretions of the urine, you can tell a great deal from it. But that is precisely the difference between today's newer medicine and the old one: the old medicine looked at the urine in the same way that one looks at a summer's day as a bright or storm-lashed summer's day, thus judging more in the rough, but, having trained itself, judged more from the facts. Today's more materialistic medicine chemically analyzes the urine, finding protein, oxalic acid, sugar and so on in it. So the difference is that one did it according to how it presented itself, and the other did it more according to chemistry.

Now, of course, in the early days, when this view was still given a great deal of consideration, people learned it properly and there were no charlatans. Today, most of those who do this are charlatans, although I am not saying that all of them are. A person can train himself so well that he can actually recognize all possible illnesses. But that requires a great deal of experience, and this experience must be applied.

Now the difference is: people today do not give much importance to the mind. The mind is almost about to be abolished. What chemistry offers can be learned by anyone. To examine a substance chemically, that is simply learned in the three, four, five, six years one spends at the university. Basically, any fool can do that, examine the substance chemically. And that is what they are striving for. The mind is to be abolished. Everyone is to be able to do the same. That was not the case in the past. In the past, the mind was highly respected. But you have to have a mind to be able to look at urine. That is the difference: in the past, people were made spiritual by being taught; today they are made into henchmen. The story is this: if you want to work, you need your hands, and your hands should be guided by your mind. Today there is much talk of manual labor and brain work, but the two should not be distinguished. Those who do manual labor should be given the opportunity to educate themselves spiritually so that they can approach the spirit just as much as the so-called intellectual workers. These distinctions can only be made among people by valuing real spiritual work. But today they want to do away with the spirit.

Well, gentlemen, you can see from this that earlier medicine placed more emphasis on looking at things directly. But that had another consequence. I don't know if you know that today's so-called scientific medicine makes rather high noses, well, you can't make them as high as today's doctor makes them, with which he looks down on the old “dirty pharmacy”, because in the past they made the remedies from all sorts of secretions. And they said to themselves: the human being secretes the secretions. If you bring them back into the body in the right way, they want to come out again. But what are they doing there? In this way, for example, they bring a sluggish astral body into regular activity or a sluggish ether body into regular activity.

Now you can say: If you find that a person's astral body has become lethargic, you could give them sweat as a remedy – you could say that. And you could say: Well, that's just the old dirty pharmacy, it really does have something like that! – Yes, the difference is not that great. If you were to look at the products used in remedies today, you would find that they are the same products found in sweat, only they are applied externally, in a mineral combination. The ancients used sweat directly. And in many ways it was more effective than what is only put together later, because, as I have shown you in many cases, nature is much cleverer than man. Man can synthesize in his remedies what nature synthesizes. The ancients did something very remarkable: they valued something that is no longer valued today. The ancients said: when a person really sweats, he actually has a whole sweat blanket around him (see drawing). — Now, that is the first thing. But a person secretes sweat all over his surface. If you could hold on to this sweat that a person secretes and take the person away – imagine what it would be like: here someone is sweating terribly; his body is covered with sweat all over the surface – imagine if I could take this person out and the sweat would remain here: That would be the whole imprint of the human being, the whole person would be there in the sweat! Very interesting, isn't it? So it is that the sweat constantly has the intention of imitating the human form.

The ancients did something else as well. They did not just look at sweat in this way, they also looked at urine in this way. Now, for example, they had a small glass of urine (see illustration on page 170). The ancients now had an even better mental image; and lo and behold: something like a ghost of a human being emerged from this urine! What sweat forms by itself, by being on the surface, emerged from the urine. In fact, in ancient times, if you had a vial of urine, you could see that. Yes, there emerged – I don't know if you know this legend, that the goddess Venus emerged from the sea foam? —a human astral specter arose from the urine. And in a person who was prone to a certain disease, let's say a person who was prone to wasting, this astral specter was thin and scrawny. In a person who, let's say, was prone to morbid fatness, this specter was swelling in all directions. Call it an illusion for my sake; it can be an illusion if you want that someone who sees a light-colored urine sees a different ghost than when he sees dark urine. But he sees it. And as an experienced doctor, he judged the illnesses accordingly.

And it was the same in the days when not only urine but also feces, the intestinal secretions, were examined. In the old days, these were particularly important for determining the diseases. Just imagine, someone had taken the intestinal secretions. You can find out that one person has a lot of sulfur in it, iron in it. Depending on what is in it, you can have more sulfurous intestinal contents. Dogs, for example, have a lot of sulfur in their intestinal contents, which then goes outwards. The more sulfur in it, the whiter and firmer the intestinal contents. The more carbon, carbonaceous matter, the softer and darker the intestinal contents; this is found in cats. Now, from the intestinal contents that come out, from the feces, you can deduce the disease much better than from the urine.

Even with intestinal contents, the ancients, shall we say, had a vision; they just had such visions. This is something very strange! With sweat, they said: When man secretes sweat, he envelops himself in his own ghost. When man secretes urine, there is his ghost in it, rising up. And in the case of intestinal contents, it is completely contained on all sides and has certain colors. And according to these - call it visions or dreams, as you like - but according to these dreams, diseases were often diagnosed in ancient times.

And in an unspecific, sometimes quite foolish way, people like the ones you mention do it by reading old books that are hard to understand today. There are also those who diagnose diseases based on feces; this usually doesn't yield much. But a person can gain a great deal of experience, and something may come of it. Only today's science doesn't pay attention to this because it prefers to examine everything chemically. But, as I said, urine analysis is just as important to today's medical science as it is to unscientific medicine, which is a remnant of ancient times.

If you leaf through old medical books, you will come across expressions that you will not usually understand. All kinds of mystics and people who always say that they have all the wisdom, not only science but also wisdom, will always tell you what they have read in old books. This is not of much value because they do not understand the old books. But if you read them, you will come across an expression. The expression mummy appears again and again. One is told: if the mummy is light, then the person is afflicted with all kinds of diseases that drive him to emaciation and so on; if the mummy is very dark, blackish, then the person is afflicted with fever, with feverish diseases. It is told everywhere what the mummy is like, and the diseases are judged by it.

What then is the mummy? If a person today reads this, they only know that these are the Egyptian mummies. Well, what do they make of it when they read that the mummy is light or dark? They don't even get what is meant. But what did the ancient people who wrote the old medical books mean? They called the form that is in the sweat and the form that emerged from the urine and feces “mummy.” The mummy was the spiritual human being. And the spiritual human being becomes visible through the secretions. And the ancients said: When the child is born, the afterbirth goes away, and the last remnant of the spiritual human being goes away. And if people could examine this today, they would find that when a small child is born, sometimes there is very little afterbirth and thus something supernatural. But there are also some where quite a lot goes away. The latter, where quite a lot goes away – there the spirit leaves at birth – they then become materialists.

And so it is, gentlemen: the spiritual activity in man, the astral and ego activity, has an extraordinary deal to do with the secretion. And when one speaks of the old dirt pharmacy, it just indicates that today one no longer appreciates what was once appreciated. Waste phenomena are no longer appreciated today. In some respects it is good not to value them too much, because all kinds of things happen. I knew someone who wanted to get rid of washing because he said – after hearing that the spirit lives in the secretions – that you should keep what is secreted, so you should also keep the dirt. And the result of that was that he came to value dirt extremely! Yes, gentlemen, all this sometimes seems foolish. But it is not always foolishness. Take horses, for example. Horses have hooves, and the hooves then merge into the soft part of the horse's toe. Dirt collects there. And if you constantly scrape away the dirt on a horse, it can become ill. You have to have an instinct for how long you have to leave the dirt so that the horse can keep up with creating it. So there you can see quite tangibly, I would say, how significant the dirt, the secretion, is. The matter is significant for the spiritual in man; it is also significant for health and illness. Health and illness can be found in the secretion. And the ancients called the spiritual in the secretion the mummy. If you find the word mummy in old writings, you will understand it from now on, because I have told you how the mummy actually comes into being: that it arises precisely from the secretion products.

As you can see, Mr. Müller's question involves a very large science, but one that can only be mastered if one delves into the spiritual. Otherwise, everything that is secreted is simply a product of secretion; no attention is paid to it. But in the secretion, the human being shows what kind of spirit he is. And that this is the case with feces is evident even from a superficial glance. Compare horse feces with cow feces. The cattle feces are larger, spread out. The horse feces are almost small heads, round. You can't help it if you have a sense of beauty – isn't it true, beauty doesn't lie in the fact that you only find odorless things beautiful – if you have a sense of beauty at all, you can't help saying when you see a cow pat: The whole cow! In it she is reflected with her broad appearance, with her casual activity, with her tendency to want to lie down; she is completely within the feces. And the horse, this jumper among animals, always wanting to get away from the earth, wanting to hop and jump out into the world – a horse's dung shows the whole horse! And so it is with the excrement of all animals, you can recognize the whole animal in them. And from this you can see what the ancients understood by mummy and what is simply astral. The supersensible animal, the supersensible human being, lives in the secretions.

With spiritual science, we can master these things. Of course, we must not allow the enemies to say that spiritual science deals with sweat, urine and so on, and that it is therefore actually a dirty science. That is what the enemies would like best!

So, gentlemen, by raising the question, I had to point out to you what is true. But you can also point out at every opportunity that it is not about any particular considerations of what is dirty, but what is spiritual. Because man becomes unconscious when the build-up in him is too strong. Then the growths arise in him when he only builds up. He must break down accordingly. He must break down. Man becomes unconscious, constantly unconscious and absent-minded, when a lump forms in the brain, because then there is only building up. The lump is built up when there is no proper breakdown in the brain. And the brain nerves arise as breakdown products, as spiritual breakdown products. Only when it gets too strong, then the blood comes in too strongly; inflammation develops. And there you have the difference between tumors and inflammations. If you have dark urine, you tend to have inflammations somewhere in the body. If you have light-colored urine, you tend to have tumors. That's one thing.
