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.
One's life is an act with no actor, and thus it has always been recognized that the insane man that has lost his mind is a parody of the sage who has transcended his ego. If one is paranoid, the other is metanoid.
The hallucination of separateness prevents one from seeing that to cherish the ego is to cherish misery. We do not realize that our so-called love and concern for the individual is simply the other face of our own fear of death or rejection. In his exaggerated valuation of separate identity, the personal ego is sawing off the branch on which he is sitting, and then getting more and more anxious about the coming crash!
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?
When I see an object there is no will; when its sensations are carried to the brain, there comes the reaction, which says "Do this", or "Do not do this", and this state of the ego-substance is what is called will
The Art of Being: A state of wholeness in which the mind functions freely and easily, without the sensation of a second mind or ego standing over it with a club.
This one life has no form and is empty by nature. If you become attached by any form, you should reject it. If you see an ego, a soul, a birth, or a death, reject them all.
