The Nature of Self: Am I My Brain?
"I" feel through my brain—feeling cells' stimulation—but am "I" "my" brain?
Even "my" brain (and my body) is perceived by "me." It is a vicious loop, except for the possibility that "I" am neither "my" brain nor "my" body. "I" can feel "my" body, then "I" must be distinct from "my" body.
If you think "I" were merely some complicated system of atoms, NO—this is "my" body, but not "me."
"I" feel information that "I" perceive as "visual info," "audio info," "smell info"... But at the end, "I" perceive an information stream which is the universe for "me." But who is the information stream's author and streamer? Definitely, it is not "me." "I" feel things "I" don't know.
Some entity must be the author of the information stream "I" feel—who authored the information and streams it! Is he God?
"I" die when "my" body can't communicate with the usual information you feel (if you're still alive), but "I" am still feeling another type of information stream.
Finally: It seems neither "me" nor God is a part of the universe (information stream).
Existence Equation:
Existence = "me" + universe (information stream, including my body) + God (author and streamer of information stream/universe)
