Written in 1908 by anonymous students of the Hermetic Philosophy, The Kybalion is a mystical guide of the Self. Originally, The Kybalion was a book of mystical doctrines, passed on from teacher to student, although the exact significance and meaning to the ancient terms have been lost for several centuries. In this book lies the Seven Principles of Hermetic Philosophy and Mental Alchemy - The Transmutation of one kind of mental vibration or state of mind into another.
