Despite what you may think, ego is not entirely bad. There is a positive aspect to it. Ego drives you to do work. A person will do a job either out of compassion or out of ego, and most of the work in society is done out of ego. Having said that, ego is also separateness and non-belongingness. It desires to prove and possess and is the shadow of doership. In itself, ego is neither good or bad. It simply is what it is.
