Let me start with a story. This is a very old symbolic story which you also might have heard. Once upon a time, the darkness went to God and made a serious complaint against the Sun. He said, “Your Sun is very badly behind me. I am very much fed up with him. He starts chasing me from the very beginning of the dawn. I am tired of running away from him the whole day. Wherever I go, he chasesme away from everywhere. In the night, I hardly take any rest when he is present. This process has been going on since millennia. What is my fault?” What harm I have caused to the Sun!”
