The Law of Thelema is an expression of timeless wisdom. The work of theurgy is to practice and understand this. Magical Theurgy presents a complete course in ritual magick and the Tarot. The book gives the extended use of elemental mudras or Godforms, meditation and Tantra-yoga plus simple and advanced magical rituals. The book includes a guide on how to make and charge magical talismans with illustrations of the Kameas or Magic Squares and sigils of the planetary spirits. Included in the Third Edition is a new compilation of the Qabalistic Key Scale magical correspondences: powers, potencies, perfumes, magical weapons, plants, gems, legendary creatures, vices and virtues. Divination is a magical means of opening and extending lines of communication between the temporal and eternal worlds. The most important function of the Tarot is as an initiatory device. The core of this book is the Grand Tarot Operation, a 30-day theurgic operation aimed at mystical and magical initiation.
