"Discourses on High Sorcery" is the third book in the series of correspondence between the Silver Elves and the founders of the Elf Queen's Daughters, particularly between Zardoa Silverstar of the first group, and Arwen Everbright of the second. While the topics range from Sorcery, Esoteric Buddhism, Elven Culture and Magic, modern culture and much else it is entitled "Discourses on High Sorcery" because the dominate theme is about the Manu, or Great Shining One, who is the inspiration and energetic guide for the evolution of humanity in this age.
