This collection of Qabalistic texts is without parallel in the history of mystical literature. Edited and introduced by Dr. Israel Regardie, the three texts included are Gematria, 777, and Sephiroth. Gematria, reprinted from "The Temple of Solomon the King," The Equinox, Vol. 1, No. 5. It provides essential explanations of theoretical and practical Qabalistic number analysis and philosophy. "An Essay in Number," also included, provides invaluable insights into key numbers as well as techniques and safeguards for practical magical work. 777 itself contains, in concise tabulated form, an overview of the symbolism of the major world religions, as well as the system of correspondence of the Hermetic Order of the Golden Dawn. In short, it is a complete magical and philosophical dictionary - a key to all religion and practical occultism - an amazing work whose value has been recognized through many editions since its first appearance in1909 and subsequent enlargement in 1995. The third text is Sepher Sephiroth, a unique dictionary listing hundreds of Hebrew words arranged by numerical value. It was compiled jointly by Crowley and Allan Bennett and first appeared in The Equinox, Vol. 1, No. 8.
