III. The Origin of Suffering
Not every form of life can renew itself from within. It must first have reached a certain higher level. Only when the force of life is strong enough constantly to endure death within itself can it awake to consciousness. To be aware of life that at every moment contains death, you need only look at life within the human being, and bear in mind what was explained in the last lecture, “Blood is a very special Fluid,” and that within human beings, life is constantly renewed through the blood. As a psychologist with insight remarked: “In the blood man carries within him a double from whom he, constantly draws strength.” But blood contains yet another force: it continuously produces death. When it has taken life-giving substances to the organs, it carries away destructive elements back to the heart and lungs. What returns to the lungs is poisonous, destructive to life.
