10. The Essence of the Human Being
What is sleep? It brings about a change in the context of the elements of human nature just described. As long as a person is awake, from morning till evening, they are intertwined and form a living system of interacting forces. It is different when a person is asleep. Desire and suffering, joy and pain, have sunk away when man lies in a deep, dreamless sleep. That all this is not present for man is because his astral body, which is the carrier of desire and suffering, has left him during sleep. Only the physical body of man, connected with the ether body, lies in bed. The astral body is outside of man as soon as he sinks into sleep. What does this astral body do during the night? Does it rest somewhere in the insubstantial? No! Precisely when we know what the astral body does at night, then we can take a deep look into the nature of the human being.
