The symbolism of the Tarot - P D Ouspensky

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. One who understands the use of symbolism in the arts, knows, in a general way, what is meant by occult symbolism. But even then a special training of the mind is necessary, in order to comprehend the "language of the Initiates", and to express in this language the intuitions as they arise.
