I have never totally understood this, but I am open to it. For me, finding myself was an internal job. I didn't need to go anywhere on the outside, but I had to explore within.
The key thing to remember when asking who am I? Is that I is, and I has. If I have something, it belongs to the I and is therefore not who I am. So, for example, my body is not me. It is mine. Same for my brain. My mind, again, it is mine. None of these things are me. I am who is asking the question, I am who owns these things. I own my mind, my body, my eyes. I can picture everything I own, can I picture me? I have learned a lot from Eckhart Tolle about how to feel the presence of myself, and for me it begins with bringing my awareness to my own body. Feeling the inside of my body with my own consciousness. From here, I can begin to dissociate with thinking, external possessions and even my body itself, as I realise that I am feeling it as it is alive around me. It is not me, it surrounds me. Once I have that sensation of aliveness in my awareness, I can bring my awareness directly to that, and away from my actual body. This again, this sensation is mine, but I am getting closer to me. Again, I find myself able to dissociate with even more thinking and possessions. Eventually, I can bring my awareness to my awareness itself, and study my consciousness. This is when I find myself. In a peaceful place, this awareness becomes my everything, and when given the space and quiet to go right in, I find myself in the place I cannot look, for I am the place that looks.
I hope this helps shed some light on yourself.
