That way is death. Even our childhood we tend to forget. And it is good to forget it. To achieve Hindu-Muslim unity the only means is to forget the past. There is a Gujarati folk-song by Ratan Bai which one hears very often.
Time is like a sieve.
We should take only the good things of history and cast off the evil. But this does not happen. Forgetfulness is necessary, and that is why the Lord has given us death. In truth, the world, as it is, is auspicious. Familiarity breeds contempt.
