Center and Circumference

I started reading a book that was recommend to me by the associate pastor at my church. It's a book written by Richard Rohr called Everything Belongs: The Gift of Contemplative Prayer. I find the title to be rather unpretentious, but I think this book is gonna be a real sleeper. I'm not trying to do a book review, but I do want to share a small snippet from the first chapter:

People who have learned to live from their center in God know which boundaries are worth maintaining and which can be surrendered... Probably the most obvious indication of noncentered ("ec-centric") people is that they are, franky, very difficult to live with. Every ego-boundary must be defended, negotiated, or worshiped: my reputation, my needs, my nation, my security, my religion, even my ball team. These are really all I have to worry about because they are my only feeble identity. You can tell if you have placed a lot of eggs in these flimsy baskets if you are hurt or offended a lot. You can hardly hurt saints because they are living at the center and do not need to protect the circumference of feelings and needs. Ec-centric persons are always a hurt waiting to happen. In fact, they will create tragedies to make themselves feel alive.

Reading this statement felt kind of like ice cubes running down my back. Where do find my true identity? Do I find my identity at the center where I am "hidden with Christ in God" (Col. 3:3), or do I find my identity along the circumference of my person?
