Is the Enneagram a religion?
A. No. We have no hard evidence that the Enneagram originated within any one religious tradition, nor that it was ever used as a stand-alone spiritual practice. One of the selling points of the Enneagram, as a map and tool for the integration of psychology and spirituality and the development of higher states of consciousness, is that it can be usefully combined with established and elaborated traditions such as Christianity, Judaism, Hinduism, Islam and Buddhism.
