Enneagram of Personality
Although some modern Enneagram of Personality writers have suggested that Ichazo's teachings are derived, in part, from those of Gurdjieff's Fourth Way work, Ichazo denied this in his "Letter to the Transpersonal Community." In July 1990, as part of a settlement with Dimension Books, each of the authors who were part of the lawsuit agreed in writing that "Oscar Ichazo is the sole originator of the theory of the ego fixations and the system of enneagons representing the different functions of the human Psyche."
