This is a story that my brother told me.

There is this candle that lives on the Sun. He is happy and bright and so is the Sun. Many many years had gone by and this candle couldn't figure out who he really is. Does he have an identity? One day, he asked a friend and the friend showed him a dark room. Sitting In the middle of the dark room, he realized that he is a bright flickering candle. Knowing that he's a candle, he returned to the Sun and lived the rest of his life as a candle.

Do I know who I am?
