One way to think about ego is as a protective heavy shell, such as the kind some animals have, like a big beetle. This protective shell works like armor to cut you off from other people and the outside world. What I mean by shell is a sense of separation: Here’s me and there’s the rest of the universe and other people. The ego likes to emphasize the “otherness” of others.
This sense of separation is an intrinsic part of the ego. The ego loves to strengthen itself by complaining—either in thoughts or words—about other people, the situation you find yourself in, something that is happening right now but “shouldn’t be,” and even about yourself. For example, when you’re in a long line at the supermarket, your mind might start complaining how slow the checkout person is, how he should be doing this or doing that, or he failed to do anything at all—including packing the bag of the person ahead of you correctly.
When this happens, the ego has you in its grip. You don’t have thoughts; the thoughts have you—and if you want to be free, you have to understand that the voice in your head has created them and irritation and upset you feel is the emotional response to that voice Only in this way can you be present to the truer world around you and see the golden shade in a pound of pears on the scanner, or the delight of a child in line who begs to eat them.The trick, of course, is to work to free ourselves from this armor and from this voice that is dictating reality.
