Lecture III
Take, first, the connection between physical body and etheric body. This connection is maintained throughout life, from conception, from the embryonic state, right until death; for it continues also through all the periods of sleep. On the other hand, the connection of these two with astral body and ego organisation is broken every time we fall asleep. Now it is essential for us to have a correct picture of how it is with ego organisation and astral body in the waking state, when they are within the physical and etheric bodies. An accurate perception of the particular way in which astral body and ego are membered into the physical and etheric bodies is indispensable if we are to be able to think intelligently about those who are suffering from so-called mental disease. It is commonly believed even among Anthroposophists—not that Anthroposophy, which is very precise in its statements, gives occasion for such a belief, but because it is so easy to cling to old and accustomed habits of thought—it is, I say, commonly believed that when the human being wakes up, his astral body and ego organisation go straight over into his physical body and etheric body, combining with them in very much the same way as hydrogen and oxygen combine in water. It is not like that. Seen clairvoyantly, it is like this[^2] If we have here the physical body, and here the etheric body, then, at the time of awaking, the astral body does certainly come in, the ego organisation also comes in; yes, they come in, and one can perceive how astral body and ego organisation, entering in, proceed to lay hold of the physical and the ether body. But this is not all. For here we meet with a fact of human life that is of great importance.
