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.
