The Kybalion

The Kybalion: Hermetic Philosophy is a 1908 book is 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. The "Three Initiates" who authored The Kybalion chose to remain anonymous. As a result, a great deal of speculation has been made about who actually wrote the book.

The most common suggestion is that The Kybalion was authored by William Walker Atkinson, either alone or with others. Atkinson was known to use many pseudonyms, and to self-publish his works. He was also the owner of the "Yogi Publication Society of Chicago", the first publisher of The Kybalion.
