I dog on the OTO a lot, but you have to give them some credit. These guys actually practice magick. They’re not just a bunch of armchair magicians (like my lazy ass can be sometimes). They are also dedicated to teaching it to others. Though it does come with a helping of Crowley worship.
Anabasis Encampment OTO – http://www.anabasis-oto.org/ A shout out to my local OTO tribe. They are currently going through what’s called MANVS ET SAGITTAE, a series of classes covering all the bases for aspiring magicians. Also check out their Youtube channel, where they perform the solitary rituals for your edification.
An Analysis of the Star Ruby – http://lionserpent.com/xxvanalysis.html After you watch it, read a detailed analysis, and marvel at all the intricate layered meanings, intended or discovered.
The Babalon Working – http://www.bibliotecapleyades.net/bb/babalon000.htm A good summary of Uncle Al and Jack Parson’s obsessions.
Rodney Orpheus – http://rodneyorpheus.com/ The celebrated author of The Grimoire of Aleister Crowley gives us two of his own rituals on his website, the Nu-Sphere Ritual, and Rite of the Infinite Stars.
The Gnostic Mass – http://www.sof-oto.org/XVSabazius.pdf An incredibly detailed, annotated pdf describing the central religious ritual of the OTO.
Assumption of the Godforms – http://www.hermetics.org/stavish/Godforms.html Sure, Crowley stole some of the godforms from the Golden Dawn, but he took them to new levels. Basic magical tools every magician should have in their arsenal.
The Rite of Pan – http://ritualchaosmagic.blogspot.com/2009/03/invocation-of-pan.html Perhaps Crowley’s most famous ritual, presented from a chaos magick perspective. How did that get in there?
