I came across this brief historical account of Aleister Crowley that coincides with the Feast of the Prophet and his Bride.
via Oxford University Press’ Blog (follow link to read entire essay):
The twelfth of August marks the Feast of the Prophet and his Bride, a holiday that commemorates the marriage of Aleister Crowley and his first wife Rose Edith Crowley in the religion he created, Thelema. Born in 1875, Crowley traveled the world, living in Cambridge, Mexico, Cairo, China, America, Sicily, and Berlin. Here, using Aleister Crowley and Western Esotericism as our trusted guide, we take a closer look at the man and his religion.
In 1898 Alesiter Crowley was initiated into the Hermetic Order of the Golden Dawn as Frater Perdurabo. The teachings of the Hermetic Order of the Golden Dawn were based upon an imaginative reworking of Hermetic writings further informed by nineteenth-century scholarship in Egyptology and anthropology. The order was structured around the symbolism of the kabbalah and organized into temples that were run on strictly hierarchical lines. Authority was vested in leading individuals, and initiates were given a rigorous and systematic training in the “rejected” knowledge of Western esotericism. They studied the symbolism of astrology, alchemy, and kabbalah; were instructed in geomantic and tarot divination; and learned the underpinnings of basic magical techniques.
Crowley’s magical self, Perdurabo, was a part of his concept of selfhood. In his own words:
As a member of the Second Order [of the Golden Dawn], I wore a certain jewelled ornament of gold upon my heart. I arranged that when I had it on, I was to permit no thought, word or action, save such as pertained directly to my magical aspirations. When I took it off I was, on the contrary, to permit no such things; I was to be utterly uninitiate. It was like Jekyll and Hyde, but with the two personalities balanced and complete in themselves.
In 1902, Aleister Crowley was a part of the team who made the second serious attempt to climb the world’s second highest summit, K2.
“Aleister Crowley and Western Esotericism, edited by Henrik Bogdan and Martin P. Starr, is the first comprehensive examination of an understudied thinker and figure in the occult.”
