The Astral Light or Anima Mundi is dual and bi‐sexual. The (ideal) male part of it is purely divine and spiritual, it is Wisdom, it is Spirit or Purusha; while the female portion (the Spiritus of the Nazarenes) is tainted, in one sense, with matter, _is_ indeed matter, and therefore is evil already. It is the life‐principle of every living creature, and furnishes the astral soul, the fluidic _perisprit_, to men, animals, fowls of the air, and everything living. Animals have only the latent germ of the highest immortal soul in them. This latter will develop only after a series of countless evolutions; the doctrine of which evolutions is contained in the Kabalistic axiom: “A stone becomes a plant; a plant, a beast; a beast, a man; a man, a spirit; and the spirit, a god.(313)” The seven principles of the Eastern Initiates had not been explained when _Isis Unveiled_ was written, but only the three _Kabalistic Faces_ of the semi‐exoteric _Kabalah_.(314) But these contain the description of the mystic natures of the first Group of Dhyân Chohans in the _regimen ignis_, the region and “rule (or government) of fire,” divided into three classes, synthesized by the first, which makes _four_ or the “Tetraktys.” If one studies the commentaries attentively, he will find the same progression in the angelic natures, _viz_., from the _passive_ down to the _active_; the last of these Beings are as near to the Ahamkâra Element—the region or plane wherein _Egoship_, or the feeling of _I‐am‐ness_, is beginning to be defined—as the first are near to the undifferentiated Essence. The former are Arûpa, incorporeal; the latter, Rûpa, corporeal.
