The so-called “Wickedest Man in the World”, Aleister Crowley has the image of being a Satanist and The Great Beast, which is mainly made by the Christian media (not the left-wing media, not the right-wing media, the Christian media). I actually briefly got interested in him because I heard from an article by Vadge Moore that he believed he was responsible for ushering in a new era of rebellion, paganism, and promiscuity. That sounded exciting to me, but, disappointingly, that’s not the real Crowley. (Incidentally though, you can read the article here; it’s still great).
See, Crowley called himself the Great Beast and 666, just to scare and shock Christians, probably because he liked to mock them and simply taking the moral high ground against them wasn’t enough. His actual beliefs are not only not Satanic, they’re not even related to actual Satanism, or even the Left Hand Path.
In Crowley’s system, a “Brother of the Left Hand Path”, or “Black Brother”, means two things. One who failed to attain the rank of Magister Templi, and one who did not destroy his ego while crossing the Abyss. In his system, called Thelema, when the adept crosses the abyss, he must surrender everything, including his self and his Holy Guardian Angel, and leap into the Abyss, and if his ego or self is completely destroyed, he becomes a “babe of the abyss”. If he does not destroy his ego, then he is referred to as a “Brother of the Left Hand Path”, who will eventually be broken up and disintegrated against his own will.
Ego-destruction is not a left hand path idea, and Crowley clearly viewed Left Hand Path as a bad thing. And while yes, he vilified celibacy in the form of The Virgin Mary, and sexuality seems to be a thing in his system, in the end, it’s meaningless compared to the final goal of destroying the ego to merge yourself as a “babe of the abyss”.
Ultimately, he was nothing more than a dark Right Hand Path thinker, whose beliefs and system often pass off as Left Hand Path.
