How is it possible to forgive and forget, sometimes it becomes impossible for me.

How is it possible to forgive and forget, sometimes it becomes impossible for me.
Sri Sri Ravi Shankar: Know that you have the power to do it and just do it. Open your mind to the vastness of this universe. Wake up and see that seven billion people are on this planet, everyday many are being burnt, everyday many are dying. Whatever big thing you are hanging on to about someone’s action towards you, know that it is your karma that made them act that way with you. If not that person, some other person would have given you the same experience. This is what you need to realize, this is what you need to see. Look at life from a bigger perspective. That’s why I keep saying,behind every event there is knowledge, behind every person there is love, behind every object there is infinity, just know this, watch this, get this, that’s it.
