Somebody I had quarreled with had gone to the authorities and succeeded in making them think that something was wrong.” [via, also]

  1. “My most memorable personal experience of the effects of black magic occurred when I was living in Scotland. The machinations of a degraded and outcast member of the Order caused my hounds to die, my servants to become insane. The struggle lasted until the recoil of the current of hated caused the luckless sorcerer to collapse.”
  2. “My enemies say that the celebration of the ‘Black Mass’ was one of the most innocuous of my activities in Sicily and in France.”
  3. “I have been accused of being a ‘black magician.’ No more foolish statement was ever made about me. I despise the thing to such an extent that I can hardly believe in the existence of people so debased and idiotic as to practice it.”
  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. “Witchcraft is a more or less solitary form of black magic.”
