When I was a small child, during the war, we were very poor and we lived in a faraway village. One day, on the road, I found the   51   pieces of a mirror. There was a Garman motorcycle accident.

I tried to find all the pieces and put them   52  , but it was not possible, so I kept only the  53    piece and I made it round. I could   54  with it as a toy and became greatly attracted by the   55  that I could reflect(反射)light to dark places where the sun would never shine—in  56 holes and some other dark places. It became a   57   for me to get light into the darkest places I could find.

I   58  the little mirror, and, as I   59  up, I would take it out when I had nothing to  do and  60  the game, As I became a   61  , I grew to understand that this was not    62  a child’s game but a metaphor(象征)for what I might do with my life. I came to    63  that I am not the light or the source of light. But light—truth, understanding, knowledge—is  64  , and it will shine in many dark places only if I reflect it.

I am just a single piece of a mirror whose   65   design and shape I do not know.    66  , with what I have I can reflect light into the dark places of this   67  —into the black places in the    68    of men—and change some things   69    some people. Perhaps others may see and do the same. This is what I am about. This is the    70  of my life.
