The Enneagram is an ancient Sufi system of classifying personality types. it comes from the Greek word "ennea" which means nine. there are nine main personality divisions within the enneagram.
ive always been interested in different methods of self discovery and the enneagram is one of the more useful methods out there in my opinion, but not a lot of people are even aware of its exsistence. there are free online tests and also many books you can purchase that deal with the enneagram. i encourage everyone to at least take one test and read up on the nine types. http://www.enneagraminstitute.com/
im a 9 with a 1 or 2 wing and self preservation instinct.
