I Make Myself Invisible in Articles by Aleister Crowley.

“It never disappeared completely. In fact, that experiment showed me that I was on the wrong track. Success lay not in an optical disappearance, but in the power of fascination. ‘Having eyes, they see not.'” [via, also]

Consider also:

  1. “I took a bungalow at Kandy and was steered through the beginnings of the art. Yoga may be taught in eight words. ‘Sit still! Stop thinking! Shut up! Get out!’ It is the learning that is difficult.”
  2. “Some of these rites were often attended with strange results. On several occasions we saw and felt a stranger among us, but when the lights were turned higher there was no one there. Our ceremonies had caused a being to take human form and be seen among us.”
  3. “My success with Yoga was so great that it became dangerous. For my own good I left it alone for two years, departing from Ceylon and going to India.”
  4. “The forces had other and worse effects. An employee (who had not touched alcohol for twenty years) suddenly got drunk and tried to murder his wife and children. This was one of many similar cases. One summer more than half my pack of bloodhounds died. My servants were always getting ill. One of the men I employed to lay down putting greens went insane and tried to murder my wife.”
  5. “Six years later I experimented again with the elixir, taking precautions to avoid such drastic results. The result was that at 47 I was as powerful an athlete as any man of 30.”
