7. How Do We Understand Illness and Death?
While the etheric body of the human being works mainly within, enlarging the organs, working from [within] outwards in reproduction, the astral body is what is there to make the outside accessible to the inside and connect it to it. This happens all the time. Every ray of light, every piece of nourishment that a person takes in, is an interaction between the person's inner being and the outside world. The regulator is the astral body, and essentially the relationship is regulated by needs, by pleasure and pain, by desire. What a person desires, he appropriates, and the faculty of desire is the expression of the astral body. [This is what man demands of his environment.] You see, then, that man fulfills various tasks through his limbs. This now requires a significant distinction to be made with regard to the limbs in the whole of human life. This distinction will become clear to us when we consider the nature of sleep. When a person sleeps, all desire and suffering, all interaction with the outside world, everything that the astral body conveys, has sunk down. No sensible person will say that a person decays in the evening and is reborn in the morning. His astral body is there, but not as it is during the day. While during the day this astral body dwells in the physical body and allows the things of the outside world to flow out through the organs of the physical body and processes them, at night it is separated from the physical body, it does not touch the physical body. This is not the case with the etheric body. What it has to do continues during sleep.
