So ego, then, is the absence of true knowledge of who we really are, together with its result: a doomed clutching on, at all costs, to a cobbled together and makeshift image of ourselves, an inevitably chameleon charlatan self that keeps changing and has to, to keep alive the fiction of its existence. . . . Ego is then defined as incessant movements of grasping at a delusory notion of "I" and "mine," self and other, and all the concepts, ideas, desires, and activity that will sustain that false construction. . . . The fact that we need to grasp at all and go on and on grasping shows that in the depths of our being we know that the self does not inherently exist. . . . {The ego's greatest triumph} is to inveigle us into believing its best interests are our best interests, and even into identifying our very survival with its own. This is a savage irony, considering that ego and its grasping are at the root of all our suffering. Yet ego is so convincing, and we have been its dupe for so long, that the thought that we might ever become egoless terrifies us.

We are in fact convinced that if we are ever to have pure knowledge of anything, we must get rid of the body and contemplate things by themselves with the soul by itself. It seems, to judge from the argument, that the wisdom which we desire and upon which we profess to have set our hearts will be attainable only when we are dead and not in our lifetime.
When desire, having rejected reason and overpowered judgment which leads to right, is set in the direction of the pleasure which beauty can inspire, and when again under the influence of its kindred desires it is moved with violent motion towards the beauty of corporeal forms, it acquires a surname from this very violent motion, and is called love.
In every one of us there are two ruling and directing principles, whose guidance we follow wherever they may lead; the one being an innate desire of pleasure; the other, an acquired judgment which aspires after excellence.
True love 's the gift which God has given To man alone beneath the heaven: It is not fantasy's hot fire, Whose wishes soon as granted fly; It liveth not in fierce desire, With dead desire it doth not die; It is the secret sympathy, The silver link, the silken tie, Which heart to heart and mind to mind In body and in soul can bind.

Yet one more item is needed to complete success, and that is the rendering of service to others in the community. Without this the mere satisfaction of selfish desire does not reach the top notch.
