who is I?

I was reading a book by Anthony De Mello, Awareness. In it, this statement stood out to me.
"Truth isn't something you can search for."
he's discussing what many zen writers have mentioned, the concept of not searching, but instead dropping your theories. dropping your opinions, your labels. which brings me to Mark 8:29. Jesus asked his followers this question: "who do you say that I am?"
wow. is there an answer? or a right or wrong one? can we know?
or for a different line of thought, don't assume the question is about Jesus. De Mello also talks about the difference between the "I" the inner self, vs the "Me." the Me is your ego, your thoughts, your beliefs, etc. the I has the ability to step outside that and look in, to examine the Me from apart. to dislocate. I can examine My thoughts. so who do I say that I am? what labels do I put on myself, my "I." human being is an easy one. not really any judgments there. but then what happens when I add "employee," "husband," "brother." then I try to live in those labels.
just some thoughts... anyone have any thoughts to add?
