III. The Origin of Suffering
Once this connection is recognized, the existence of pain becomes comprehensible. It is pain that originally gave rise to consciousness. When the life within a being is exposed to light, air, heat or cold, then these external elements act in the first place on the living being. This influence does not give rise to consciousness in plants because here the effects are simply absorbed. Consciousness only arises when there is conflict between the external elements and the inner life-force, causing a breaking down of tissue. Consciousness can only arise from the inner destruction of life. Unless a partial death takes place in the living being, the process that gives rise to consciousness cannot be initiated; beams of light cannot penetrate to the surface of life, causing partial destruction of the inner substances and forces. It is this that produces the mysterious process that is occurring everywhere in the external world.
