The popular use of the Enneagram of Personality (as contrasted with the use of enneagrams within the Arica School) began principally with Claudio Naranjo who had studied with Ichazo in Chile. Ichazo considered Naranjo's understanding of the Enneagram to be limited and incomplete. Naranjo's major contribution to the Enneagram of Personality was his addition of defense mechanisms to the model developed by Ichazo: "His contribution to the Enneagram successfully joined the insight and methods of a mystical path of transformation with the intellectual power of a Western psychological model."
