V. Connections Between Organic Processes and the Mental Life of Man

If you now study the liver in the manner I have just explained in regard to the lungs, you will discover that there are concentrated in the same way within the liver all the forces which in the next incarnation determine the inner disposition of the brain. Again by a detour through the metabolic organism of the present life, the forces of the liver pass over, this time not into the shape of the head, but into the inner disposition of the brain. Whether or not someone is to be an acute thinker in the next incarnation depends upon how he behaves in the present one, in order that thus, upon the detour through the metabolism there may arise within the liver definite powers. But if these are ejected during the present incarnation they lead to hallucinations or to powerful visions.
