Grant provides an exhaustive and critical study of Crowley’s system of sexual magick and the strange rites which he practiced and advocated for the purpose of promoting the Law of Freedom with its formula of “Love under Will”. The book reveals the occult workings of the Fire Snake or Kundalini-Goddess, the cosmic power in man which, when awakened by magical means, assumes an external form identified by Crowley as the Scarlet Woman, she who influences the secret power-zones in the body of man and invokes the Hidden God.
