Good and bad are just two sides of the same coin. When the mind is giving importance, it calls it good or bad. And nothing is worthy of great importance. No event in the past deserves such seriousness. Nothing is to be called so important. Only the present is important.
But we want to keep good memories. Whenever you will try to keep good memories, you will find that along with you are also keeping lots of bad memories. If good is important then bad is also important. But our attempt is, “let me retain all the good memories and let me forget all the bad memories.” That is impossible. That cannot happen. That is against the law of the mind. In fact, the more bad memories you have, the good memories will appear all the sweeter.
You see, a lion was coming to eat you and you were going to be surely killed. A stranger comes and saves you. You want to keep only the good part of it and forget the bad part. Is it possible? You want to remember only that you were saved by a stranger, but the moment you remember that you were saved by a stranger, you will also have to remember that you were about to be killed.
