We all have blindspots in our character and personality. Just like in a vehicle, if you drive without paying attention to your blindspots, then you will run over stuff.
We share a story about how the enneagram helped us understand our 14 year old son.
The enneagram is sort of a personality test, but it assumes that the personality we have is a coping mechanism, a false self, that we have developed to deal with the world around us. We share the structure of the enneagram with the 3 centers of intelligence. We talk about the growth process involved with learning about your number.
The Enneagram is opened sourced - meaning that no one person owns it.
We really like this test because of the pie chart result it gives.
