A clear and concise book explaining the root principles of magic in everyday terms. Filled with fascinating philosophies it was one of Regardies favourite works (and one of the first I read). Now reprinted it is an excellent source for both beginner and experienced magician alike. This is not a book containing set out rituals, but rather as its title suggests, a study in magic. It incorporates many systems and discusses them well. Subjects include yoga, qaballah, egyptian magic, the astral light, Divinity, training of the magician, the will, invocation and many more. A must for every occult library.
