If you have to have it, it's ego. If you have to not have it, it's ego. Hold life lightly and it will deliver what you need and release what you don't.
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?
This intelligence itself is modified into what we call egoism, and this intelligence is the cause of all the powers in the body. It covers the whole ground, sub-consciousness, consciousness, and super-consciousness.
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!
"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."
When you drop the ego, you drop a whole world that you have created around it. For the first time you are able to see things as they are - not as you would like them to be. And when you are capable of knowing the facts of life, you become capable of knowing the truth. The facility of life is the first step towards truth. And ego is the most falsifying agent.
