I. Soul and Spirit in the Human Physical Constitution

Waking life and sleeping life may therefore also be studied from this point of view. When we are asleep our warmth organism is permeated by the cosmic spirituality which on waking we drive out through our Ego, for in waking life it is the Ego that brings about in the warmth organism what is otherwise brought about by the cosmic spirituality. It is the same with the cosmic astrality; we drive it out when we wake up and readmit it into our organism when we fall asleep. Thus we can say: By leaving our body during sleep, we allow the cosmic spirit to draw into our warmth organism, and the world-soul, or the cosmic astrality, into our airy organism.
