Geez. So apparently I wasn't reading Lon Milo DuQuette's The Magic of Aleister Crowley, but Rodney Orpheus' Abrahadabra. I apparently mixed the two up cause Lon Milo wrote the preface to Orpheus' book, and only found out after I finished it (just now)! A thousand apologies and admirations to Rodney Orpheus (and Lon Milo DuQuette too! Why not?!). I really recommend this to anyone wanting to turn their life more magickal. A short but most excellent primer on Thelema, the O.T.O., Kabbala, and much more. There is a sample chapter here.
