The country called Si-dzang by the Chinese, and Tibet by Western geographers, is mentioned in the oldest books preserved in the province of Fo-kien (the chief headquarters of the aborigines of China) as the great seat of occult learning in the archaic ages. According to these records, it was inhabited by the "Teachers of Light," the "Sons of Wisdom" and the "Brothers of the Sun." The Emperor Yu, the "Great" (2207 B.C.), a pious mystic, is credited with having obtained his occult wisdom and the system of theocracy established by him for he was the first one to unite in China ecclesiastical power with temporal authority from Si-dzang. That system was the same as with the old Egyptians and the Chaldees that which we know to have existed in the Brâhmanical period in India, and to exist now in Tibet namely, all the learning, power, the temporal as well as the secret wisdom were concentrated within the hierarchy of the priests and limited to their caste. Who were the aborigines of Tibet is a question which no ethnographer is able to answer correctly at present. They practise the Bhon religion, their sect was pre-buddhistic and anti-buddhistic, and they are to be found mostly in the province of Kam that is all that is known of them. But even that would justify the supposition that they are the greatly degenerated descendants of mighty and wise forefathers. Their ethnical type shows that they are not pure Turanians, and their rites now those of sorcery, incantations, and nature-worship remind one far more of the popular rites of the Babylonians, as found in the records preserved on the excavated cylinders, than, as alleged by some, of the religious practices of the Chinese sect of Tao-sse a religion based upon pure reason and spirituality. Generally, little or no difference is made even by the Kyelang missionaries who mix greatly with these people on the borders of British Lahoul and ought to know better between the Bhons and the two rival Buddhist sects, the Yellow Caps and the Red Caps. The latter of these have opposed the reform of Tzong-ka-pa from the first, and have always adhered to old Buddhism, so greatly mixed up now with the practices of the Bhons. Were our Orientalists to know more of them, and compare the ancient Babylonian Bel or Baal worship with the rites of the Bhons, they would find an undeniable connection between the two. It is out of the question to begin an argument here to prove the origin of the aborigines of Tibet as connected with one of the three great races which superseded each other in Babylonia, whether we call them the Akkadians (invented by F. Lenormant), or the primitive Turanians, Chaldees and Assyrians. Be it as it may, there is reason to call the Trans-Himâlayan esoteric doctrine Chaldæo-Tibetan. And, when we remember that the Vedas came agreeably to all traditions from the Mansarova Lake in Tibet, and the Brâhmans themselves from the far north, we are justified in looking on the esoteric doctrines of every people who once had or still have them, as having proceeded from one and the same source, and to thus call it the "Âryan-Chaldæo-Tibetan" doctrine, or Universal Wisdom Religion. "Seek for the Lost Word among the hierophants of Tartary, China and Tibet," was the advice of Swedenborg, the seer.
