Yah2

"Y-ha-ho was a sacred word in the Egyptian mysteries, which signified 'the one eternal and concealed deity' in nature and in man; i.e., the 'universal Divine Ideation,' and the human Manas, or the higher Ego" (TG 375). Yaho in consequence must not be confused with Yehowah or Jehovah, for Jehovah was merely the inferior reflection in the higher material worlds of the spiritual light called Yaho. Yaho, therefore, is equivalent in type, standing, and character to atman, the universal, of theosophical literature.
