Lecture III

So that we can say: here are the physical and etheric bodies of the human being, and during sleep the astral body and ego-organization are outside. The ego-organization gives us our sense percepts and sensations when we are awake. There is no sense perception during sleep, because the ego-organization is not in the physical and etheric bodies and because the ego is not receptive for impressions from the environment during that time. Likewise, the astral body gives us thoughts when it is in the physical and etheric bodies, but when it is outside it is not sensitive to things in the world and it gives us no impressions.
