By Rudolf Steiner

GA 128

Steiner discusses here the supersensible systems of forces and their relationship to the physical organs. He focuses on the digestive and respiratory systems, the differentiation of conscious and subconscious processes in the organs, the "warmth" function of the blood and its effect on the ego, and the evolutionary process implicit in the formation of the spinal column and the brain.
