Renowned occult writer, Manly P. Hall, not only explores the history and images of the tarot cards, but he delves into the secret occult symbolism while examining the divinatory meaning behind each of the 22 major arcana. Manly P. Hall quotes Eliphas Levin, stating: with no other book than the Tarot, if he knew how to use it, could in a few years acquire universal knowledge, and would be able to speak on all subjects with unequalled learning and inexhaustible eloquence.
