Rather than converting base metals into gold, Hermetic alchemists focused on elevating their mental forces to a higher level. The precepts of their philosophy remained shrouded in secrecy for more than 2,000 years, clouded by obscure language and dense allegories. This guide offers a modern interpretation of Hermetic doctrine, distilling its teachings into seven compelling principles that can be applied to self-development in daily life. For centuries, the legendary Egyptian man-god Hermes Trismegistus — regarded as the father of astrology, alchemy, and other magical arts — inspired writers and readers of occult literature. In 1908, the anonymous authors known as "Three Initiates" prepared this concise and engaging edition of the master's teachings. It outlines the Hermetic principles and then examines them in depth, offering direct quotations from the source material, followed by clear explanations. The best introduction to Hermeticism for beginners and adepts alike, this definitive edition of one of esoteric literature's classics explores principles relevant to any religious, spiritual, or magical tradition.
