Once again, I have had a message quoting Crowley at me! "Do what thou wilt shall be the whole of the law". But he never actually said it! (Although he did write it!).
I heard Crowley speak many times, both in person and on the radio. To me he sounded quite insane! A lot of sense mixed with a lot of rubbish.
What Crowley actually said was "Do what thou wilt, so long as you are willing to take the consequences of what you do."
He often said, "Believe what you will!"
That's a bit different from "doing" what you will.
A great deal of Crowley's writing is difficult to understand. You must not take his words as the literal truth. You must remember that he was a drug addict, and often "mixed up" in his own Mind!
Many people in my lifetime thought that Crowley was evil, wicked! But was he really? Evil, or just slightly mad!
Was he a sex maniac? Well, many thought so. But then, the sexual instinct is very strong in lots of people; perhaps in him, more so!
Remember also the Christian adage, "Forgive them; for they know not what they do!"
