The Symbolism of the Tarot by P.D. Ouspensky. From the foreword:
“No study of occult philosophy is possible without an acquaintance with symbolism, for if the words occultism and symbolism are correctly used, they mean almost one and the same thing. Symbolism cannot be learned as one learns to build bridges or speak a foreign language, and for the interpretation of symbols a special cast of mind is necessary; in addition to knowledge, special faculties, the power of creative thought, and a developed imagination are required.”
