Psychosynthesis from Problems on the Path of Return by Mark Stavish, M.A. in Vol 3 No 1 of Caduceus.
“How one makes these attempts at parallels between the Tree of Life and psychological models such as presented by Psychosynthesis is somewhat arbitrary. Exact matches across the board rarely occur. Function is what designates similarity, and function in Kabbalah is often a matter of perspective more than anything else. Several models exist for placing the Worlds on the Tree as well as their psycho-spiritual functions. The models put forth by Z’ev ben Shimon Halevi are quite different from the generally accepted Golden Dawn models of the psyche. However, since it is these models, derived from interpretations of late 19th and early 20th century British occultism that most students are familiar with, it is their designations of the Worlds and Sepherotic functions that will be applied.” [via]
