Theres very little I can add to the previous reviewers comments regarding this, as they've pretty much spelt it out how excellent Crowley's master-opus is. Simply, if you're a Thelemite, Occultist or a Crowley fan in general - you need this!!!! It also gives proof to any intelligent & open mind, that far from being the drug-addled poseur so many people unfairly paint Crowley as, that this is penned by a man who deserved a damn sight more respect in his lifetime as a genius of occultism with a brand of philosophy that some people are still scared witless by. All in all, its one of the very few books Ive splashed out on, that has re-paid thrice the amount I paid for it and even more. This book together with Lon Milo Duquette's "The Magick of Thelema", will show you the way. "There is no law beyond Do What Thou Wilt, Love Is The Law, Love Under Will".
