Black Magic is Not a Myth in Articles by Aleister Crowley.

“This is supposed to release the powers of evil and bring them into alliance. (It is rather the case of the mouse trying to make a friend of the cat!)” [via, also]

Consider also:

  1. “The effect is completely ridiculous compared with the waste of spiritual forces required to produce it.”
  2. “One day, without warning, I woke up to find that I had lost all my maturity. I became mentally and physically a stupid stripling. The only thing I could think of doing was to cut down trees! I was living in a cottage in New Hampshire; for fifteen hours a day I toiled at felling trees. I worked like a madman. No feat of strength was too great for me.”
  3. “Through their mediumistic acts, spiritists sometimes get hold of disintegrated pieces of the mental apparatus of a man or woman who has died recently.”
  4. “In the congregational form of the Black Mass the priest, having finished his abominations–these are, quite frankly, indescribable–scatters the fragments of the Host on the floor, and the assistants scramble for the soiled fragments, the possession of which, they believe, will allow them to work their petty and malicious designs.”
  5. “The ‘Black Mass’ is a totally different matter. I could not celebrate it if I wanted to, for I am not a consecrated priest of the Christian Church. The celebrant must be a priest, for the whole idea of the practice is to profane the Sacrament of the Eucharist. Therefore you must believe in the truth of the cult and the efficacy of its ritual.”
