Dion Fortune is justly regarded as one of the foremost occultists of modern times, an acknowledged adept whose clear, concise, and down-to-earth approach has been responsible for bringing knowledge of the occult sciences to a much wider reading public. 'The Esoteric Philosophy of Love and Marriage' is one of her earliest books, in which she describes the occult meaning of marriage and love as manifestations of the principle of Sex or Polarity, a universal force that functions from the highest to the lowest planes of existence. Topics covered include the Ideal Marriage, the Karmic ties between souls, how souls find their mates, and the esoteric teaching concerning 'twin souls'. The book's stance on such topics as contraception, masturbation and abortion may appear puritanical to modern eyes, but Dion Fortune gives solid esoteric reasons for her statements, reasons that raise questions concerning the wisdom of today's moral relativism. A must-read for any occultist interested in one of the most fundamental aspects of life on this, and all other, planes of existence.
