The subjective "I" seems universal to me. I have it, my wife has it, my dog has it. Donkeys have it. So, can this Maury expression claim "awareness" is just mine? In a sense, yes, because the expression is unique in its particulars.
On the other hand, I sense the subjective awareness in others, unique, yes, but the same basic subjective sense of "I". For me, seeing that this sense appears universal, and I just arrived here with it, something else is responsible for it. I'm just living out this particular instance. Whatever is the origin and what to call it is another matter.
I seem to have lost my sense of doership. It's a bit scary. There's much to be acknowledged as "unknown." But that's okay. It's seems rather peaceful to be done with having to perfect an ego. Not that I don't have a personal sense of "I", but it just seems rather insignificant. I just enjoy what is when I can, and suffer the slings and arrows when I can't.
