The Qabbalah, the Secret Doctrine of Israel [Illustrated]

"A doctrine so logical, so simple, and at the same time so absolute. The necessary union of ideas and signs, the consecration of the most fundamental realities by the primitive characters; the Trinity of Words, Letters, and Numbers; a philosophy simple as the alphabet, profound and infinite as the Word; theorems more complete and luminous than those of Pythagoras; a theology summed up by counting on one's fingers; an Infinite which can be held in the hollow of an infant's hand; ten ciphers and twenty-two letters, a triangle, a square, and a circle,--these are all the elements of the Kabalah. These are the elementary principles of the written Word, reflection of that spoken Word that created the world!"
(Albert Pike, in "Morals and Dogma")
