I talked to Chris Heuertz about the ideas in his book, The Sacred Enneagram. We go into detail, using my type (4) and his (8) as examples.
“Far more than a personality test, the Enneagram’s 9 profile types offer what author Chris Heuertz calls a sacred map to the soul. Lies about who we think we are keep us trapped in loops of self-defeat. But the Enneagram reveals both the nine ways we got lost, and the nine ways we find our way home to our True Self and to God.”
