I have posted a number of times on both my blogs (find posts here and here) about the benefits of understanding psychosynthesis. When I was participating in a two-year intensive in mediation, a 10-day training in psychosynthesis was required. Over the decades since, I frequently have been grateful for my knowledge of psychosynthesis, so much so that I took a several day refresher course a couple of years ago. In short, I highly recommend to any mediator that he or she learn more about this approach and philosophy, at least by reading the books listed over to the right by Assagioli and Ferrucci.
About a year ago, an article about the neuroscience of psychosynthesis was published by the Association for the Advancement of Psychosynthesis. It was written by Piero Ferrucci, a man who studied with Roberto Assagioli, the founder of psychosynthesis, and who is very skilled at explaining Assagioli's gift to us. Because I was so impressed with the article, I am shocked that I did not link to it before now. What's that cliche? Better late than never?
From "Psychosynthesis in the Light of Neuroscience":
Many studies in neuroscience show us psychosynthesis in action (without calling it that) in all its important aspects. Studying neuroscience in this context is like learning psychosynthesis again from a different, more concrete perspective. In this essay—by no means an exhaustive treatment of the subject, which would require much more space—I will highlight some basic themes that psychosynthesis and neuroscience have in common.
You likely will recognize several of the names Ferrucci references, including Jeffrey Schwartz, Mario Beauregard, and Daniel Siegel. Click to read the article. I enthusiastically recommend it!
