The Etheric Being in the Physical Human Being

When we look back upon the sleeping human being, we see that when he falls asleep and goes out with his Ego and astral body, there arises a kind of vegetable activity in the organism abandoned by the astral body and Ego. There is activity in man's inner being and we feel that the first moments of sleep are like the beginning of a vegetative process; to the clairvoyant, sleep appears as if the body were pervaded by the growing life of plants. Imaginative knowledge enables us to perceive this. This vegetation, however, does not grow in the same way as that upon the earth. It is possible to describe this, to meditate over such things, for then we progress further and further.
