I. Soul and Spirit in the Human Physical Constitution

Now consider the following. The etheric body remains in us also during sleep, from the moment of falling asleep to the moment of waking; therefore the interworking of the Chemical Ether and the etheric body continues within our being, via the fluid organism, also while we are asleep. It is different in the case of the astral body and feeling. From the moment of falling asleep to the moment of waking, the astral body is outside the human organism; then the astral body and feeling do not then work upon the air organism, but the air organism—connected as it is with the whole surrounding world—is sustained from outside during sleep. And the human being, with astral body and feeling, goes out of the body and passes into a world with which it is related primarily through the Light Ether. While asleep we live directly in an element that is transmitted to our astral body by the air organism during waking life. We can speak in a similar way of the Ego and the warmth organism.
