Quote from : The Heart of the Master & Other Papers Book

The ethical aspect of the Law of Thelema is simple enough theoretically. "Do what thou wilt" does not mean "do what you please"; though this degree of emancipation is implied, that we can no longer say that any given course of action is "wrong". Every man and and every woman has an absolute right to do his or her true will. At the same time, to quote , "... thou hast no right but to do thy will". So then, the new Law really announces a stricter bondage than any previous law and this in accordance with biological teaching. An organism progresses by self-imposed inhibitions.
