This scholarly work creates a new epoch in traditional occult philosophy. It is the first contemporary encyclopedic exposition of the great Western Tradition since the basic books by Eliphas Lévi and Papus, and it also has full practical utility. The Philosophical Tarot has always been recognized as a universal key to all wisdom attainable by human beings. This text will be of particular interest, because of its kindred approach, to the many readers of the extraordinary contemporary masterpiece Meditations on the Tarot, by an anonymous writer much valued in esoteric circles throughout the world. The present work is by no means just a theoretical treatise accessible only to specialists, for anyone can understand the initiatory concepts of Mouni Sadhu's Tarot, perceiving completely new horizons of thought, activity, psychology, cosmology, and practical esotericism. In this text a great number of questions which occur to the earnest seeker are answered in a new and fascinating way, and the solution of the philosophical equations arising from the Arcana opens new vistas in every field of life. The book is suitably subdivided into 100 separate lessons, allowing for systematic study.
