The sense of self is kind of at the core of human suffering because it feels as if we are separate from the rest of nature. We have these thoughts that are brain based thoughts but then the I swoops in to make a decision. In some sense, it goes so deep that it says if the I is separate from the physical world. Even feeling like a lonely eye in this bigger universe there's a sense of being a part of something larger than yourself and this is intrinsically positive for human beings.
