Who knows what our relationship has been with someone who is causing us difficulties now? Who knows what we may have done to him in another life! If we respond to such people with retaliation, we are just locking ourselves into that same cycle. We are going to have to keep replaying this part of the movie again and again in this and future lifetimes. The only way to break out of the cycle is by changing our attitude.
