1. The Enneagram is believed to be derived from an extensive body of secret and sacred knowledge, possibly dating back to Sufi mysticism.
2. In the hands of contemporary interpreters it has evolved into a powerful system for personal, spiritual, and professional understanding of human personality.
3. The Enneagram symbol is a two-dimensional, nine-pointed figure enclosed in a circle, consisting of crisscrossing lines that connect nine points, or enneatypes.
4. Each enneatype is infinitely nuanced, and the types all overlap so descriptive qualifiers can be too limiting.
5. The numbers are neutral markers. For example, a Seven isn't healthier, more evolved, or somehow inherently better than a Two.
6. Everyone possesses qualities and characteristic behaviors of each enneatype, but everyone only has one enneatype.
7. Your enneatype is not who you are; it is what you habitually and consistently do.
8. Your enneatype does not change. You evolve or devolve within its parameters.
9. All the enneatypes are gender neutral.
10. You have a secondary energy (a wing, located on either side of your type on the Enneagram circle) and two connecting points (a security point and a stress point) that influence your behavior.
