Enneagram of Personality
Oscar Ichazo (1931–2020) is generally recognized as the principal source of the contemporary Enneagram of Personality which is largely derived from some of Ichazo's teachings, such as those on ego-fixations, holy ideas, passions and virtues. The Bolivian-born Ichazo began teaching programs of self-development in the 1950s. His teaching, which he calls "Protoanalysis", uses the enneagram figure among many other symbols and ideas. Ichazo founded the Arica Institute which was originally based in Chile before moving to the United States and coined the term "Enneagram of Personality".
