And which one is the “must read” for anyone interested in reading the works of this mage?

Direct answers are much appreciated. (that is, no fundy sermons, please. I go to a Hindu temple when I’m in the mood for that.)
Please, folks, don’t make me feel sorry I asked. Yeah, of course I can loiter around a book store. I dunno . . . when someone asks a Q about meditation or philosophy or something, I provide an intelligent answer based on my knowledge of the subject. I’m just asking for the same consideration.

Any Thelemites out there who can speak on this?
I gave up on you Answers folks and asked a friend who follows Thelema who gave me an appropriate answer.
