Bill Duvendack has successfully bridged the Realms, Orders and Arch-Demons of the Qliphoth into the subject of Astrology. His insights allow the Black Magician to dissect themselves in way that gives greater control over themselves by knowing what demons are intimately connected to them and in what way they are connected. This self-knowledge which can be deciphered to the desired degree is priceless for the serious student of the Qliphoth. I highly recommend this book for both beginners and advanced students of the Qliphoth alike.
