EGO by Iqbal 1 - Invading Act

Inner experience is the ego at work. We appreciate the ego itself in the act of perceiving, judging, and willing. The life of the ego is a kind of tension caused by the ego invading the enviroment and the environment invading the ego.
The ego does not stand outside this arena of mutual invasion. It is present in it as a directive energy and is formed and disciplined by its own experience.
