As says the Commentary:
If thou would'st understand the Secondary [“Creation,” so-called], O Lanoo, thou should'st first study its relation to the Primary.[260]
The First Race had three Elements, but no Living Fire. Why? Because:
“We say four Elements, my Son, but ought to say three,” says Hermes Trismegistus. “In the Primary Circle,” or Creation that which is marked [Symbol: Like a large letter H, with dots above and below, and tildes above and below] reads “Root,” as in the Secondary likewise.
Thus in Alchemy or Western Hermeticism—a variant on Eastern Esotericism—we find:
Sulphur ... Flamma ... Spiritus
Mercury ... Natura ... Aqua
Salt ... Mater ... Sanguis
And these three are all quaternaries completed by their Root, Fire. The Spirit, beyond Manifested Nature, is the Fiery Breath in its absolute Unity. In the Manifested Universe, it is the Central Spiritual Sun, the electric Fire of all Life. In our System it is the visible Sun, the Spirit of Nature, the terrestrial God. And in, on, and around the Earth, the fiery spirit thereof—Air, fluidic Fire; Water, liquid Fire; Earth, solid Fire. All is Fire—Ignis, in its ultimate constitution, or I, the root of which is 0 (nought) in our conceptions, the All in Nature and its Mind. “Pro-Metor” is divine Fire. It is the Creator, the Destroyer, the Preserver. The primitive names of the Gods are all connected with fire, from Agni, the Âryan, to the Jewish God who is a “consuming fire.” In India, God is called in various dialects, Eashoor, Esur, Iswur, and Îshvara, in Sanskrit, the Lord, from Isha, but this is primarily the name of Shiva, the Destroyer; and the three chief Vedic Gods are Agni (Ignis), Vâyu, and Sûrya—Fire, Air, and the Sun, three Occult degrees of Fire. In the Hebrew, אזא (Aza) means to “illuminate,” and אשא (Asha) is “Fire.” In Occultism, to “kindle a fire” is synonymous to evoking one of the three great Fire-powers, or to “call on God.” In Sanskrit the root Ush is fire or heat; and the Egyptian word Osiris is compounded, as shown by Schelling, of the two primitives Aish and Asr, or a “fire-enchanter.” Aesar in the old [pg 121] Etruscan meant a God, being perhaps derived from Asura of the Vedas. Îshvara is an analogous term, as Dr. Kenealy thought, who quotes the Bhagavad Gitâ to the effect that:
Îshvara resides in every mortal being and puts in motion, by his supernatural powers, all things which mount on the wheel of time.
