The Thoth tarot deck is one of the most popular today; its lucid, interconnected, and rich depth of symbolism is rewarding and thought-provoking. The artwork is excellent, the symbolism behind it compelling. Crowley's "Book of Thoth" is an excellent book for both the beginner and more advanced students, serving as an introductory work pointing out multiple rewarding paths of study for the interested student to pursue, from astrology to Kabbalah to Thelema's philosophy. One of his most accessible works, the writing style is lucid and entertaining, mixing a well-presented wealth of information with dry and frequently perverse humor. One of the best Tarot books you will ever own, period.
