MAGICK is Crowley's masterpiece, the work into which he poured his knowledge of the Astral and other planes. It is in three parts, the first two of which treat of the principles of Yoga, and of Ceremonial Magic as taught in Golden Dawn where he served his apprenticeship from 1898 to 1900. The third and major part, which was written mainly in his Abbey of Thelema in Sicily between 1920 and 1923, contains his own system of practical occultism. Crowley's Magick is a doctrine and a technique for establishing contact with extra-terrestrial entities - spirits, demons, elementals - for the purpose of extending human consciousness and expanding life to cosmic proportions. He replaced the Ceremonial rites as taught in the Golden dawn by rites of a sexual kind. These were developed from Tantric and Alchemical sources. From Tantra he formed his own method of arousing the Kundalini force; from Alchemy he derived a technique for transmuting the sexual energies into elixirs of magical potency. The whole of Crowley's doctrine is based on The Book of the Law in which the future of humanity - the establishment on earth of a New Order - is outlined. John Symonds is Crowley's literary executor and biographer; Kenneth Grant is the World Head of the Order of Oriental Templars (O.T.O).
