I was doing a lot of digging into the MBTI and Enneagram sections of youtube this weekend, and ran across a plethora of amazing information. One piece, which I was more struck by than any other, was this interview with Claudio Naranjo (often referred to as the "Mother" of the Enneagram of Personality). I found this interview extremely illuminating, as he tells all kinds of stories about his life, his time at the Arica Institute in Chile with Oscar Ichazo (the "Father" of the Enneagram of Personality), G.I. Gurdjieff (the teacher of the Ancient Enneagram [not of personality, but the symbol and its meaning itself]), Esalen, Fritz Perls, SAT (his group, "Seekers After Truth", which he started in Berkeley in the 70s, and from which sprang forth most of the Enneagram teachers we know today), et al.
I've been considering starting this thread for a while, and I figure it can serve as a place to share information anybody comes across about Naranjo, whether video, audio, written, or anything else they might deem applicable.
