"Understand the process of the ego. How does the ego live? The ego lives in the tension between what you are and what you want to be. A wants to be B - the ego is created out of this very tension. How does the ego die? The ego dies by you accepting what you are. That you say, "I am fine as I am, where I am is good. I will remain just as existence keeps me. Its will is my will."
The pest of society are the egotist, they are dull and bright, sacred and profane, course and fine. It is a disease that like the flu falls on all constitutions.
Throw overboard all idea of jealousy and egotism, once for all. Come on to the practical field with tremendous energy; to work, in the fullness of strength! As to the rest, the Lord will point out the way.
Ego is the movement of the mind toward objects of perception in the form of grasping, and away from objects in the form of aversion. This fundamentally is all the ego is. This movement of grasping and aversion gives rise to a sense of a separate 'me,' and in turn the sense of 'me' strengthens itself this way.
You sharpen the human appetite to the point where it can split atoms with its desire; you build egos the size of cathedrals; fiber-optically connect the world to every eager impulse; grease even the dullest dreams with these dollar-green, gold-plated fantasies, until every human becomes an aspiring emperor, becomes his own God... and where can you go from there?
