I found the following clips useful and although some are long, I did not want to cut them off. I leave it up to you to move on if they don't speak to you. Clips 2,5 are about the enneagram system in general, 3 is a quick test you may choose to take, while 4 is a common criticism. We begin with a wonderful motivational clip, and end with an interview with Claudio Naranjo, one of the original thinkers behind the modern enneagram system. (personal note: Naranjo lived in Berkeley in his later years and worked with Ravenna Helson at the Institute of Personality Assessment and Research; she was the wife of my thesis advisor, Henry Helson. All three left us in the 2010's.)
