Chapter 2 of A New Earth is titled, Ego The Current State Of Humanity. Ego is identification with thought forms, emotional forms and any thing that we are attached to that gives us a sense of self. The more we have, the more we know, the more we do, the better we are in the eyes of the ego... in the first section of this chapter Eckhart explains that instead of using words as linguistic conventions we use them essentially as ego enhancers and through labeling things it gives us a sense of superior intellect, the illusion that we know a lot, and as the ego dictates more is better... Through labeling things we often cover up their true nature. It's ok not to know, it's actually a relief from upholding a facade that we do have all the answers.
