V. Sickness and Healing
The relation to the human astral body is quite different. We have already seen from previous descriptions that the astral body is only an outward fact, so to speak, for the truly clairvoyant consciousness; the latter can see the astral body in the same way as the physical one only by schooling the consciousness as has been frequently described. In ordinary life the astral body of the human being is not observable from the outside; the eye can only see the outer expression of the instincts, desires, passions, thoughts and feelings which surge through it. But in contrast, the human being observes within himself these experiences of the astral body. He observes what we call the instincts, desires, passions, joy and sorrow, pleasure and pain. Thus it can be said that the relationship between the astral and the physical body is such that in normal life we observe the former internally, but the physical body externally.
