Is my face a mirror of my soul? I can see my hands, my legs, but I can not see my own face. So how can I understand what happens in me? I can take a looking-glass and see a tired man in it. And that is all. No information, only a touch of glance to the surface. I take a sheet of paper and a pencil, and every thing from inside of me begins to reflect on the smooth surface of the paper.
