People widely recognize Dion Fortune as one of the most influential occultists of the contemporary era. He is a recognized expert whose approach is transparent, succinct, and grounded in reality. As a result, he has been responsible for making knowledge of the occult sciences accessible to a much larger reading audience. In one of her first writings, The Esoteric Philosophy of Love and Marriage, she portrays the occult meaning of marriage and love as expressions of the principle of sex, or polarity, a universal force that operates from the highest to the lowest levels of existence. In this book, she reveals the occult meaning of marriage and love. For example, some of the topics discussed include the ideal marriage, the karmic bonds between souls, the process by which souls choose their spouses, and the esoteric doctrine about 'twin souls'. She gives strong esoteric reasons for her remarks, justifications that raise issues about the wisdom of today's moral relativism. The book's attitude on matters like contraception, masturbation, and abortion may look puritanical to contemporary eyes, yet Dion Fortune provides these reasons. Any occultist who is interested in one of the most essential components of life on this level of existence, as well as all other planes of existence, should undoubtedly read this book.
