The second trinity of the Tree of Life: Chesed, Geburah, and Tiphereth.
“Why is it called ethical? It is simply because ethics or upright behaviour is primed there. There, we know the might of the Law; there, we know good and evil, about what is good and evil. This triangle is the World of Pure Spirit, which is Atman, Buddhi, Manas that is, the Hindu Trimurti. Obviously, the center of gravity in this triangle becomes at a simple glance the Human Soul; that Soul who suffers and who gives that human part to us, the Sephirah Tiphereth that coincides with the Causal Body. This triangle is also denominated as the Triangle of the Son. Here we find the Cosmic Christ, Chokmah who when so endowed manifests himself through the Human Soul, which is Tiphereth in the Hebraic Kabbalah.” - Samael Aun Weor, Tarot and Kabbalah
