THE EDGE
"Existentially and energetically, the edge is the state which we may approach intentionally or quite unconsciously in which there is a risk of being radically other than we are typically.
This can describe situations where physical death is imminent, social death is close (annihilation of the social self), the void is encountered, and all situations of entering a zone of *ineffable potential............................"
Dr. Ralph Locke
*ineffable- indescribable- incapable of being expressed in words.
