<b>The Kybalion </b>is a book originally published in 1908 by &quot;<b>Three Initiates</b>&quot; (often identified as the New Thought pioneer <b>William Walker Atkinson</b>, 1862&ndash;1932) that purports to convey the teachings of <b>Hermes Trismegistus</b>. While it shares with ancient and medieval Hermetic texts a number of traits such as philosophical mentalism, the concept of &#39;as above, so below&#39;, and the idea that everything consists of gendered polar opposites, as a whole it is more indebted to the ideas of modern occultist authors, especially those of the New Thought movement to which Atkinson belonged. A modern Hermetic tract, it has been widely influential in New Age circles since the twentieth century.
