What is your opinion on Aleister Crowley?

As a Thelemite, I agree that Crowley held a profound knowledge of religion and magic. Most of what you have written above is true. Crowley was a flawed and complex character, but there is no doubt that his books hold great power for those capable of absorbing them, and that "every man and woman is a star" as written in Liber AL (The Book of the Law).
