@maija @Verfassungsschmutz Stephen Flowers. He translates/writes his own books about a variety of pagan and occult literature, and he has a suspiciously large amount of books (once you get over 10 on the same subject you know the person is most likely a hack)
Ran into him bc he's one of the few who publishes thorough studies on occultism rooted in NAZI Germany, but most of his books are just on generic left hand path stuff, with several specifically about indulging in immorality for spiritual gain. When one of them was about BDSM I cringed to death. Julius Evola was already pushing it with Metaphysics of Sex
