“The symbolic power of the Enneagram comes out of [an] ancient tradition that views geometry as sacred - as revealing an archetypal patterning or order that structures the growth process of living things, whether it be the petals of a flower, the unfurling of a fern, the dimensions of a seashell, or the development of the human psyche.”
