As we know it was G.I. Gurdjieff who first introduced the enneagram to the western world.
For some reason the translation of the enneagram has somewhat changed since then.
I have studied at a Gurdjieff school and I was taught there are only 6 essence types.
There are many sites on the internet about the enneagram and nearly all of them tell of nine types.
I am confused as to why and perhaps this explains why on this site you find the enneagram test to be not so accurate.
Scientists discovered quarks inside the atom a few years ago and surely its no coincidence that each quark exhibits the same characteristics as each essence type - even to the point of pairing up with its soulmate.
Personally I think this is an important link between religion and science and has been sadly missed due to a simple misunderstanding of the enneagram.
