Some more thoughts, because I just can't stop when the ball is rolling...
Science already shows, quite clearly that we are not our "ego." The ego is indeed an avatar. Why? Because everything you see around you, the colors, the objects, the sound, the shadows, in short, everything in your consciousness, is in your brain, a responsive representation of outside information. You are the "screen" where everything is displayed. So if you identify with your body or the space behind your eyes, you are suffering a magnificent illusion, because that "point in space" exists in a space that is wholly already inside the representation your brain creates.
You are the whole, no single part within it.
In the West Hume was one of the first philosophers to point out that try as you might, you can't find a the "ego" behind the eyes, or anywhere else, if you stop for a second and try. Then you will realize that you have an implicit, abstract belief in something that is not really there in the concrete; in other words a kind of illusion. I.e the "ego" is an illusion.
If we apply this insight to Descartes we find that the sentence, "I think, therefore I am," really can only mean "there is thinking going on," but who is aware of this thinking? Is thinking aware of itself? If you pay close attention, you find that no, thinking is not aware of itself, but speaks like the explicit word and is located specifically inside the whole conscious representation or field, and is understood within that complete light. Therefore, "Consciousness IS."
Finally, Kant nearly became an idealist because it was difficult to understand how consciousness could grasp anything outside itself. Whenever we are conscious of something, it is our consciousness that we are directly experiencing, not the thing itself. Kant grappled with how to get an objective science out of this position, and we are still largely living in his shadow.
If we want to unify Spirituality (What am I?) and Science (What is the World?) what is the best way to go from here?
