The Kybalion
By Three Initiates

"The Kybalion: Hermetic Philosophy is a 1908 book claiming to be the essence of the teachings of Hermes Trismegistus, published anonymously by a group or person under the pseudonym of "the Three Initiates". [...] The book purports to be based upon ancient Hermeticism, though many of its ideas are relatively modern concepts arising from the New Thought movement."
