Do what thou Wilt shall be the whole of the Law.
I say this because it's always on the coffee table, or bedside table, or in my backpack, or wherever I was reading it last. This book both provokes thoughts as well as gives advice. If I could give only one 5 star review this would be it. With the depth involved in the book either it was truly written by a praeter-human intelligence named Aiwass or Crowley was praeter-human himself in his very early career. I nominate it best book of the Aeon.
Love is the Law; Love under Will.
