Enneagram of Personality

[Ilkka]

I did happen to hear/read about this Enneagram of Personality some time ago and I was curious to see that there is a similarity in my personality found from that enneagram.

What I would like to know is that is there some other means of having to know different personalities? Maybe this might help others to see more about themselves, of their behaviour in certain situations. Also this might be good tool to use in Sanctuary as well, if there is not a better one of course.
