An exploration of a system of magical practice which works through the sublimation of erotic energies between two or more people. Polarity magic is a concept of occult study that is often shrouded in complexity and confusion. Now, established author John Michael Greer explains its place in Western ceremonial tradition, providing a guidebook to using polarity magic a powerful, effective and balanced way of working magic in order to enhance and deepen magical practice. Polarity magic does not involve sexual intercourse, but rather relies on the movements of the ether (the force behind life itself) which people experience during sexual or emotional attraction. When these movements follow their natural course to the material plane, they result in sex or childbirth. When redirected to less material, more spiritual, planes, however, they produce magical and powerful results. The book covers a broad expanse of expertly researched information, laid out in a clear and accessible prose. It ranges from an introduction to the history of polarity magic; situations polarity magic in the macrocosm and microcosm; information on how to prepare for polarity magic; the practice of both basic and advanced polarity magic, as well as mass polarity magic. The Secret Wisdom of Sex is an invaluable tool for practitioners of ceremonial magic wanting to explore the fascinating workings of polarity magic.
