The triumph of physical love leads not only to the enjoyment or reproduction of one's own kind, but rises to ethereal duplicates of physical bodies, creating karmic bonds that connect souls in many incarnations. The very etymology of the Latin word sex, as well as the Russian sex, expresses the idea of separation, half, duality. The most important thing in the definition of eroticism is the assertion of the idea of Dida . This is exactly what Dion Fortune's book is about. It can help to understand why there are so few truly happy marriages on Earth, why divorces are so frequent. Maybe it will allow someone who has not yet met his Couple to avoid a catastrophic mistake... This is a book about how souls find their partners. Sublimation of the Life Force will release previously unthinkable creative possibilities of the mind The consequence of doing Fortune's suggestions in the second part of the book of spiritual exercises will be a change in your relationships with people, for they will allow you to acquire an amazing quality known as personal magnetism. And, since this book is the last in this select collection of Fortune's writings, in the Appendix we offer you her Dictionary of Esoteric Terms and a passage of Death by Vivien Le Fay Morgan, which may interest those who have read her esoteric novels in the first two volumes.
