From the RS article: "Parsons was also a follower of the English occultist Aleister Crowley. Parsons befriended Hubbard and invited him to move onto his estate. In one of the stranger chapters in Hubbard's life, recorded in detail by several biographers, the soon-to-be founder of Dianetics became Parsons' assistant -- helping him with a variety of black-magic and sex rituals, including one in which Parsons attempted to conjure a literal "whore of Babalon [sic]," with Hubbard serving as apprentice."
Doesn't matter what you call them ('Satanist' or 'Black majik')-- Parsons, Crowley and Hubbard were deeply disturbed men.
