"I visualize the human nervous system as being imbedded in the cell tissue of the body just as the roots of a tree are imbedded in the ground which gives it nourishment. One end of the nervous system we recognize as being in the brain. It is here that all of the messages from the body and the sense organs are localized. The other end of the nervous system is imbedded directly in cell tissue through a countless number of fine nerve endings. These nerve endings end in cup shaped groups of cells called blastulas.
