Watts states it like this:

I find that the sensation of myself as an ego inside a bag of skin is really a hallucination. What we really are is, first of all, the whole of our body. And although our bodies are bounded with skin, and we can differentiate between outside and inside, they cannot exist except in a certain kind of natural environment. Obviously a body requires air, and the air must within a certain temperature range. The body also requires certain kinds of nutrition. So in order to occur the body must be on a mild and nutritive planet with just enough oxygen in the atmosphere spinning regularly around in a harmonious and rhythmical way near a certain kind of warm star.

That arrangement is just as essential to the existence of my body as my heart, my lungs,and my brain. So to describe myself in a scientific way, I must also describe my surroundings, which is a clumsy way getting around to the realization that you are the entire universe. However we do not normally feel that way because we have constructed in thought an abstract idea of our self.

"Well," you ask."How do I get rid of it?" And my answer to that is: That's the wrong question. How does one get rid of what? You can't get rid of your hallucination of being an ego by an activity of the ego. Sorry, but it can't be done. If you try to get rid of your ego with your ego you will just end up in a vicious circle. You'd be like somebody who worries because they worry because they worry.
