Nature wants us to react, to return blow for blow, cheating for cheating, lie for lie, to hit back with all our might. Then it requires a super divine power not to hit back, to keep control, to be unattached. - Swami Vivekananda
This is what Stephen Covey says - Between every stimulus and response, you have time to think, this is you are response'able' and hence you are responsible to whatever you do. If we can utilize this think time to stop hating people, forgiving people and spreading love, the world should be much more lovely place to live.
