A term which appertains solely to the more recondite teachings of occultism, of the esoteric philosophy. Little can be said here about it except to state that it is the source of the human aura as well as of everything else that the human septenary constitution contains. It is usually of an oviform or egg-shaped appearance, whence its name. It ranges from the divine to the astral-physical, and is the seat of all the monadic, spiritual, intellectual, mental, passional, and vital energies and faculties of the human septiform constitution. In its essence it is eternal, and endures throughout the pralayas as well as during the manvantaras, but necessarily in greatly varying fashion in these two great periods of kosmic life.
