8. The Mystery of Death and the Riddle of Life
If we want to explore the sources of life in the sense of the theosophical worldview, we must remember the structure of the human being. What the senses see in a person is only a part of the human being, which it shares with so-called mineral beings. Spiritual science shows us how the physical organism is kept alive by a second principle of human existence, the etheric or life body, which is a continuous fighter against the disintegration of the physical body. Furthermore, we have seen from the study of Theosophy how everything that lives in the soul in the way of pleasure and suffering, joy and pain, instincts, desires and passions, has a third member in the human being as a carrier – the astral body. While the physical body is shared with all mineral beings, the etheric body is shared with all living beings, but the astral body is shared only with animals. The sum of powers, that which the human being has at the center of his being, he is able to summarize with the words “I am.” The “I am” is proper only to man among all the living beings around him.
