An aspect of Gurdjieff's teachings which has come into prominence in recent decades is the enneagram geometric figure. For many students of the Gurdjieff tradition, the enneagram remains a koan, challenging and never fully explained. There have been many attempts to trace the origins of this version of the enneagram; some similarities to other figures have been found, but it seems that Gurdjieff was the first person to make the enneagram figure publicly known and that only he knew its true source. Others have used the enneagram figure in connection with personality analysis, principally with the Enneagram of Personality as developed by Oscar Ichazo, Claudio Naranjo and others. Most aspects of this application are not directly connected to Gurdjieff's teaching or to his explanations of the enneagram.
