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 Kybalion was first published in 1908 by the Yogi Publication Society and is now in the public domain, and can be found on the internet. The book purports to be based upon ancient Hermeticism, though many of its ideas are relatively modern concepts arising from the New Thought movement. The book itself early in reading makes the claim that it makes its appearance in one’s life when the time is appropriate and includes variations of material found in the book of Proverbs.
Mental Transmutation (also described as Mental Alchemy, the Art of Mental Chemistry, and the Art of Polarization) refers to the art of changing and transforming one’s own mental states and conditions, as well as influencing those of others. It is also called a form of “Mystic Psychology”.
