Who am I

So who am I? There is this centre I can sense it. That really sees. That really feels. That really hears. That really experiences all.
My first challenge is that I for approaching this question I only have my current framework. To begin with I have a face. This "who am I?" does not seem to have  a face. How am going to deal with me not having a face? or not even a body? Then there is this body of memories that makes me what I am. How can I approach a Who am I question that discards all past and is just present?

Then there is this paradox that Who am I is asking the question too( and who is writing right now)..like sephiroth. So I need to hold the tail and go back to the source. Or just catch the "I am" when "I" see it as the watcher or the listener. Just sticking close to it. But I find that I dont have the pool of attention to stay long enough before the secret is  revealed to me. Almost like an underwater dive where I cant hold my breath beyond a limit.
Then there is the gradual approach. Of being in the Iam as much as possible. More a feeling supported by a breathing inside.A feeling of my breath brushing against a corner of the heart on the right side of the body in the in breath.
But when I look at the eye that is looking through my physical eye I see its localisation in a different place.

This is the other problem. One of localisation of who am I in space, Because  "I am" is supposed to pervade all space how can i localise it using my body as the measure?

Activity and Action. This is the other approach. That I do nothing and let things happen because "It"  has   a better idea of the lay of the land inside me. Activity of doing tasks or various spiritual practices - do they come in the way? Are they done so that the "mind" is happy that something is being done and energy engaged? Is spiritual practices the greatest deception? And all one needs to try is to allow things to happen?
But its not simple I feel. Where does one get the strength to overcome fear? because I cannot receive when one is closed. And fear is the energy that closes. Makes us closed. And not let "It" do its thing?
How do I transmute fear?
