You may be interested in checking out a newly available PDF of an updated David Beth (author of Voudon Gnosis, past leader of Ordo Templi Orientis Antiqua & La Couleuvre Noire, and member of La Société Voudon Gnostique) essay “Aleister Crowley and the Dawn of Aiwass” which has a number of notes which reference Aleister Crowley’s Liber AL vel Legis sub figurâ CCXX as delivered by (LXXVIII) XCIII unto DCLXVI with a commentary by The Beast To Mega Therion 666.
The post about this essay over at LAShTAL notes that David Beth is making this available “[a]s a gift to the Thelemic community for their inspiration and their aid in research and ideas in the past” and that “David considers this one of his finest non-Voudon related writings and invites conversation and feedback on it.”
