SEX MORALITY 129 cissoid, there isn't one. Mind your own business! is the sole sufficient rule. To drag in social, economic, religious and such aspects is irrelevance and impurity. 3. The Magical side. Sex is, directly or indirectly, the most powerful weapon in the armoury of the Magician; and precisely because there is no moral guide, it is indescribably dangerous. I have given a great many hints, especially in Magick. and The Book of Thoth-some of the cards are almost blatantly revealing; so I have been rapped rather severely over the knuckles for giving children matches for playthings. My excuse has been that they have already got the matches, that my explanations have been directed to add conscious precautions to the existing automatic safeguards. The above remarks refer mainly to the technique of the business; and it is going a very long way to tell you that you ought to be able to work out the principles thereof from your general knowledge of Magick, but especially the Formula of Tetragrammaton, clearly stated and explained in Magick, Chapter III. Combine this with the heart of Chapter XII and you've got it! But there is another point at issue. This incidentally, is where the "automatic safeguards" come in. "Thou hast no right but to do thy will" (AL, I: 42) means that to "go awhoring after strange" purposes can only be disastrous. It is possible, in chemistry, to provoke an endothermic reaction; but that is only asking for trouble . The product bears within its own heart the seed of dissolution. Accordingly, the most important preliminary to any Magical operation is to make sure that its object is not only harmonious with, but necessary to, your Great Work. Note also that the use of this supreme method involves the manipulation of energies ineffably secret and most delicately sensitive; it compares with the operations of ordinary Magick as the last word in artillery does with the blunderbuss! What is the damn thing, anyway?
