Paul Foster Case’s An Introduction to the Study of the Tarot (1920) is a foundational text treating the tarot as a symbolic map of esoteric wisdom, rather than just a divination tool. It connects tarot to the Kabbalah, astrology, and Western mystery traditions, encouraging meditation on symbols to unlock deeper spiritual insights. The book is aimed at serious students interested in occultism and the mystical, rather than predictive, aspects of tarot, serving as a precursor to his later work, How to Read The Tarot.
