E.A. Koetting author of The Nine Demonic Gatekeepers saga
I have always hated math, therefore, I never studied astrology. But I love this new book by Bill Duvendack, Qliphothic Astrology. He doesn’t place the emphasis of astrology on the math, but more on the Qliphothic Demonology and magick behind the astrology. My favorite part of this book is where he gets into the real workings of the different Tunnels of Set, taking off from where Kenneth Grant left off, and pushing that knowledge forward. He applies the mysteries of the stars to your rituals, to your black magick, to the Left Hand Path, and to the Shadow Work that you’re engaging in.
