What IS an Enneagram style?

An Enneagram style is technically an ego-state, that is a cluster of characteristics held in place by a narrow focus of attention, an energy flow that derives from it, a world view and a group of inner processes (strategies) that we repeat until they are habits.
These patterns of attention, energy expenditure, expectations and responses to extenal realities amount to a trance. A trance is generated from within, an automatic habit of including and excluding certain information and a habitual way of responding to information.
You all know people about whom you say, "Oh, I can't tell him that, he can't hear that." You are describing his trance.
Our trances are our most common form of mendacity - we don't lie by saying what is not true, we lie by not seeing what is true.
An Enneagram trance is active and dynamic, it is the unconscious patterns by which we do a lot of our thinking. What I do as an Enneagram coach is help you see those patterns and then interrupt them.
