“That there are fearful secrets in nature may well be believed when, as we have seen in the case of the Russian Znachar, the sorcerer cannot die until he has passed the word to another, and the hierophants of White Magic rarely do. It seems as if the dread power of the “Word” could only be entrusted to one man of a certain district or body of people at a time. When the Brahmatma was about to lay aside the burden of physical existence, he imparted his secret to his successor, either orally, or by a writing placed in a securely fastened casket which went into the latter’s hands alone. Moses “lays his hands” upon his neophyte, Joshua, in the solitudes of Nebo and passes away forever. Aaron initiates Eleazar on Mount Hor, and dies. Siddhartha-Buddha promises his mendicants before his death to live in him who shall deserve it, embraces his favorite disciple, whispers in his ear, and dies; and as John’s head lies upon the bosom of Jesus, he is told that he shall “tarry” until he shall come.
Like signal-fires of the olden times, which, lighted and extinguished by turns upon one hilltop after another, conveyed intelligence along a whole stretch of country, so we see a long line of “wise” men from the beginning of history down to our own times communicating the word of wisdom to their direct successors. Passing from seer to seer, the “Word” flashes out like lightning, and while carrying off the initiator from human sight forever, brings the new initiate into view. Meanwhile, whole nations murder each other in the name of another “Word”, an empty substitute accepted literally by each and misinterpreted by all!
We have met few sects which truly practice sorcery. One such is the Yezidis, considered by some, a branch of the Koords, though we believe erroneously. These inhabit chiefly the mountainous and desolate regions of Asiatic Turkey, about Mosul, Armenia, and are found even in Syria, and Mesopotamia. They are called and known everywhere as devil-worshippers; and most certainly it is not either through ignorance or mental obscuration that they have set up the worship and a regular inter-communication with the lowest and the most malicious of both elementals and elementaries.
They recognize the present wickedness of the chief of the “black powers”; but at the same time, they dread his power, and so try to conciliate to themselves his favors. He is in an open quarrel with Allah, they say, but a reconciliation can take place between the two at any day; and those who have shown marks of their disrespect to the “black one” now, may suffer for it at some future time, and thus have both God and Devil against them. This is simply a cunning policy that seeks to propitiate his Satanic majesty, who is no other than the great Tcherno-bog (the black god) of the Variagi-Russ, the ancient idolatrous Russians, before the days of Vladimir.”
