“Some of the things Aleister said to me,” Grady replied carefully, “could be interpreted as hints pointing that way.” He went on to quote Crowley’s aphorisms about various of the standard entities contacted by Magick. The Abramelin spirits, for instance, need to be watched carefully. “They bite,” Aleister explained in his best deadpan am-I-kidding-or-not? style. The Enochian “angels,” on the other hand, don’t always have to be summoned. “When you’re ready, they come for you,” Aleister said flatly.
(The Enochian entities were first contacted by Dr. John Dee in the early 17th Century. Dr. Dee, court astrologer to Queen Elizabeth and also an important mathematician, has been controversial from his own time to ours, some writers regarding him as a genius of the first rank and others as a clever lunatic. 

According to two interesting books, “The World Stage” and “The Rosicrucian Enlightenment,” both by a most scrupulous historian, Dr. Francis Yates, Dee was almost certainly a prime mover in the “Illuminati” and “Rosicrucian Brotherhoods” of that time, which played a central role in the birth of modem science. The alleged UFOnaut from Uranus which communicated with the two Naval Intelligence officers gave a name, AFFA, which is a word in the “angelic” language used by the entities Dee contacted. It means Nothing. George Hunt Williamson also got some words in “angelic” from his Space Brothers, remember.)
