“Following the Christian dogmas seriatim, if we concentrate our attention upon one which provoked the fiercest battles until its recognition, that of the Trinity, what do we find? We meet it, as we have shown, northeast of the Indus; and tracing it to Asia Minor and Europe, recognize it among every people who had anything like an established religion. It was taught in the oldest Chaldean, Egyptian, and Mithraitic schools. The Chaldean Sun-god, Mithra, was called “Triple”, and the trinitarian idea of the Chaldeans was a doctrine of the Akkadians, who, themselves, belonged to a race which was the first to conceive a metaphysical trinity.
The Chaldeans are a tribe of the Akkadians, according to Rawlinson, who lived in Babylonia from the earliest times. They were Turanians, according to others, and instructed the Babylonians into the first notions of religion. But these same Akkadians, who were they? Those scientists who would ascribe to them a Turanian origin, make of them the inventors of the cuneiform characters; others call them Sumerians; others again, respectively, make their language, of which, (for very good reasons), no traces whatever remain – Kasdean, Chaldaic, Proto-Chaldean, Kasdo-Scythic, and so on.
The only tradition worthy of credence is that these Akkadians instructed the Babylonians in the Mysteries, and taught them the sacerdotal or Mystery language. These Akkadians were then simply a tribe of the Hindu-Brahmans, now called Aryans – their vernacular language, the Sanscrit of the Vedas; and the Sacred or Mystery-language, that which, even in our own age, is used by the Hindu fakirs and initiated Brahmans, in their magical evocations. It has been, from time immemorial, and still is employed by the initiates of all countries, and the Thibetan lamas claim that it is in this tongue that appear the mysterious characters on the leaves and bark of the sacred Kounboum.
Jacolliot, who took such pains to penetrate the mysteries of the Brahmanical initiation, in translating and commenting upon the Agrouchada-Parikshai, confesses the following: “It is pretended also, without our being able to verify the assertion, that the magical evocation were pronounced in a particular language, and that it was forbidden, under pain of death, to translate them into vulgar dialects. The rare expressions that we have been able to catch, like – L’rhom, h’hom, sh’hrum, sho’rhim, are in fact most curious, and do not seem to belong to any known idiom.”
Those who have seen a fakir or a lama reciting his mantras and conjurations, know that he never pronounces the words audibly when preparing for a phenomenon. His lips move, and none will ever hear the terrible formula pronounced, except in the interior of the temples, and then in a cautious whisper. This, then, was the language now respectively baptized by every scientist, and, according to his imaginative and philological propensities, Kasdeo-Semitic, Scythic, Proto-Chaldean, and the like.”
