This is essentially the argument for the soul: it holds reality together, it is my offscreen director, my presiding intelligence. I can think, talk, work, love, and dream, all because of the soul, yet the soul doesn't do any of these things. It is me... Everything that makes the difference between life and death must cross into this world via the soul... Soul is a connection between the world of the five senses and a world of inconceivable things like eternity, infinity, omniscience, grace, and every other quality unmanifest.
For sheer adventure, exploring the inner space of the human spirit has to equal the exploration of outer space. Inner space holds a realm of existence not readily apparent when we are in the grip of the strident external world. A powerful launching vehicle for the discovery of the realm within is silence. It is in the vessel of silence that inner transformation can occur.
