“It must not be inferred, on that account, that such a mysterious brotherhood is but a fiction, not even a name, though it remains unknown to this day. Whether its affiliates are called by an Egyptian, Hindu, or Persian name, it matters not. Persons belonging to one of these sub-brotherhoods have been met by trustworthy, and not unknown persons, besides the present writer, who states a few facts concerning them, by the special permission of one who has a right to give it.
In a recent and very valuable work on secret societies, K. R. H. Mackenzie’s Royal Masonic Cyclopaedia, we find the learned author himself, an honorary member of the Canongate Kilwinning Lodge, Number 2 (Scotland), and a Mason not likely to be imposed upon, stating the following, under the head, Hermetic Brothers of Egypt:
“An occult fraternity, which has endured from very ancient times, having a hierarchy of officers, secret signs, and passwords, and a peculiar method of instruction in science, religion, and philosophy. If we may believe those who at the present time, profess to belong to it, the philosopher’s stone, the elixir of life, the art of invisibility, and the power of communication directly with the ultramundane life, are parts of the inheritance they possess. The writer has met with only three persons who maintained the actual existence of this body of religious philosophers, and who hinted that they themselves were actually members. There was no reason to doubt the good faith of these individuals – apparently unknown to each other, and men of moderate competence, blameless lives, austere manners, and almost ascetic in their habits. They all appeared to be men of forty to forty-five years of age, and evidently of vast erudition…their knowledge of languages not to be doubted. They never remained long in any one country but passed away without creating notice.”
Another of such sub-brotherhoods is the sect of the Pitris, in India. Known by name, now that Jacolliot has brought it into public notice, it yet is more arcane, perhaps, than the brotherhood that Mr. Mackenzie names the “Hermetic Brothers”. What Jacolliot learned of it, was from fragmentary manuscripts delivered to him by Brahmans, who had their reasons for doing so, we must believe. The Agrouchada Parikshai gives certain details about the association, as it was in the days of old, and, when explaining mystic rites and magical incantations, explains nothing at all, so that the mystic L’om, L’Rhum, Sh’hrum, and Sho-rim Ramaya-Namaha, remain, for the mystified writer, as much a puzzle as ever. To do him justice though, he fully admits the fact, and does not enter upon useless speculations.”
