" Shameful confession, one of my own Chelas (or so it is rather incredibly reported to me) said recently: "Self-discipline is a form of Restriction." (That, you remember, is "The word of Sin.") Of all the utter rubbish! (Anyhow, he was a "centre of pestilence" for discussing the Book at all.) About 90 percent of Thelema, at a guess, is nothing but self-discipline. One is only allowed to do anything and everything so as to have more scope for exercising that virtue.

Concentrate on "Thou hast no right but to do thy will." The point is that any possible act is to be performed if it is a necessary factor in that Equation of your Will. Any act that is not such a factor, however harmless, noble, virtuous or what not, is at the best a waste of energy. But there are no artificial barriers on any type of act in general. The standard of conduct has one single touchstone. There may be—there will be—every kind of difficulty in determining whether, by this standard, any given act is 'right' or 'wrong'; but there should be no confusion. No act is righteous in itself, but only in reference to the True Will of the person who proposes to perform it. This is the Doctrine of Relativity applied to the moral sphere. "
