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. 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. There are many methods for developing the "sense of symbols" in those who are striving to understand the hidden forces of Nature and Man, and for teaching the fundamental principles as well as the elements of the esoteric language. The most synthetic, and one of the most interesting of these methods, is the Tarot.
