The Kybalion is a concise work on The Hermetic Philosophy outlining seven universal principles - Mentalism, Correspondence, Vibration, Polarity, Rhythm, Cause and Effect, and Gender. Rather than the actual Kybalion, this is purportedly an exegesis on that text. The Kybalion: Hermetic Philosophy is a 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".
