Tattva

Tattva (devanāgarī: तत्त्व) is a Sanskrit word meaning "principle, essence, reality."

Adi-Tattva

ÂDI TATTVA, the primordial universal Force, issuing at the beginning of manifestation (or creative period) from the eternal immutable SAT, the substratum of ALL. It corresponds with the Auric Envelope or “Brahmâ’s Egg,” surrounding every globe, as every man, animal and thing. It is the vehicle containing potentially everything––Spirit and Substance, Force and Matter. It is Âdi Tattva that we refer to in Esoteric Cosmogony, as the Force which proceeds from the First or Unmanifested Logos.
