(or the Triangle of Priesthood) The third trinity of the Tree of Life: Netzach, Hod, and Yesod.
“The third triangle becomes very interesting because this is the Magical Triangle formed by the mind or Netzach, the Astral Body or Hod, and the Ethereal Body or Yesod, which is also the basic sexual principle of Universal Life. Why this is called the Magical Triangle? Undoubtedly, it is because High Magic is exercised in the kingdom of the mind and the kingdom of the Astral and even in the Klipoth or the Infernal Worlds.” - Samael Aun Weor, Tarot and Kabbalah
