Chaldæan Theology contemplated three great divisions of supra-mundane things:-- the First was Eternal, without beginning or end, being the "Paternal Depth," the bosom of the Deity. The Second was conceived to be that mode of being having beginning but no end; the Creative World or Empyræeum falls under this head, abounding as it does in productions, but its source remaining superior to these. The third and last order of divine things had a beginning in time and will end, this is the transitory Ethereal World. Seven spheres extended through these three Worlds, viz., one in the Empyraeum or verging from it, three in the Ethereal and three in the Elementary Worlds, while the whole physical realm synthesized the foregoing. These seven spheres are not to be confounded with the Seven material Planets; although the latter are the physical representatives of the former, which can only be said to be material in the metaphysical sense of the term.Prior to the supramundane Light lay the "Paternal Depth," the Absolute Deity, containing all things "in potentia" and eternally immanent. This is analogous to the Ain Suph Aur of the Kabalah, three words of three letters, expressing three triads of Powers, which are subsequently translated into objectivity, and constitute the great Triadic Law under the direction of the Demiurgus, or artificer of the Universe.
In considering this schema, it must be remembered that the supramundane Light was regarded as the primal radiation from the, Paternal Depth and the archetypal noumenon of the Empyræum, a universal, all-pervading -- and, to human comprehension -- ultimate essence. The Empyræum again, is a somewhat grosser though still highly subtilized Fire and creative source, in its turn the noumenon of the Formative or Ethereal World, as the latter is the noumenon of the Elementary World. Through these graduated media the conceptions of the Paternal Mind are ultimately fulfilled in time and space.
Without entering at length into the metaphysical aspect, it is important to notice the supremacy attributed to the "Paternal Mind." The intelligence of the Universe, poetically described as "energising before energy," establishes on high the primordial types or patterns of things which are to be, and, then inscrutably latent, vests the development of these in the Rectores Mundorum, the divine agents or powers already referred to. As it is said, "Mind is with Him, power with them."
The word "Intelligible" is used in the Platonic sense, to denote a mode of being, power or perception, transcending intellectual comprehension, i.e., wholly distinct from, and superior to, ratiocination. The Chaldæans recognised three modes of perception, viz., the testimony of the various senses, the ordinary processes of intellectual activity, and the intelligible conceptions before referred to. Each of these operations is distinct from the others, and, moreover, conducted in separate matrices, or vehicula. The anatomy of the Soul was, however, carried much farther than this, and, although in its ultimate radix recognised as identical with the divinity, yet in manifested being it was conceived to be highly complex. The Oracles speak of the "Paths of the Soul," the tracings of inflexible fire by which its essential parts are associated in integrity; while its various "summits," "fountains," and "vehicula," are all traceable by analogy with universal principles. This latter fact is, indeed, not the least remarkable feature of the Chaldæan system. Like several of the ancient cosmogonies, the principal characteristic of which seems to have been a certain adaptability to introversion, Chaldæan metaphysics synthesize most clearly in the human constitution.
In each of the Chaldæan Divine Worlds a trinity of divine powers operated, which synthetically constituted a fourth term. "In every World," says the Oracle, "a Triad shineth, of which the Monad is the ruling principle." These "Monads" are the divine Vice-gerents by which the Universe was conceived to be administered. Each of the four Worlds, viz., the Empyræan, Ethereal, Elementary and Material, was presided over by a Supreme Power, itself in direct rapport with "the Father" and "moved by unspeakable counsels." These are clearly identical with the Kabalistic conception of the presidential heads of the four letters composing the Deity name in so many different languages. A parallel tenet is conveyed in the Oracle which runs: "There is a Venerable Name projected through the Worlds with a sleepless revolution." The Kabalah again supplies the key to this utterance, by regarding the Four Worlds as under the presidency of the four letters of the Venerable Name, a certain letter of the four being allotted to each World, as also was a special mode of writing the four-lettered name appropriate thereto; and, indeed in that system it is taught that the order of the Elements, both macrocosmic and microcosmic, on every plane, is directly controlled by the "revolution of the name." That Name is associated with the Æthers of the Elements and is thus considered as a Universal Law; it is the power which marshals the creative host, summed tip in the Demiurgus, Hypezokos, or Flower of Fire.
