Sorry Nix, I'm not exactly a metaphysical genius *shrug*.
So CHIM is knowing you're basically a part of something else, but being able to say, "So what, I'm still who I am?"
Pretty much, yes. If you believe the concept of the Godhead but fail to retain your individuality - as to say, "So you mean I'm just a part of a dream?" - then you will zero-sum. Zero-summing means that the part of the Godhead that is you has woken up, and you will cease to exist. That means that when you believe the Godhead, one of two things will happen, depending on your perception: you will either achieve CHIM, or zero-sum.
In Matrix (this is the only time I would ever compare the Matrix to CHIM), Neo is able to bend the spoon when he knows it isn't real. This is
similar to the concept of CHIM (note: similar,
not exact). When you achieve CHIM, you understand that you are everything. That means, pretty much, you can do whatever you can imagine. It means that you have effectively become a God.
So why have the ones that achieved CHIM not conquered the world? It is because they know that they already
are the world. They have become all-knowing beings, and they would have no use for conquering the world. You could say that they are so powerful, they know that there is no need.
