If we ourselves remain angry and then sing world peace, it has little meaning. First, our individual self must learn peace.
This we can practice. Then we can teach the rest of the world.
Heartache is good. Accept it joyously. Allow it, don't repress it. The natural tendency of the mind is to repress anything that is painful. By repressing it you will destroy something that is growing. The heart is meant to be broken. It's purpose is to melt into tears and evaporate. When the heart has evaporated exactly in the same place where the heart was, you come to know the deeper heart.
No man ever got very high by pulling other people down. The intelligent merchant does not knock his competitors. The sensible worker does not work those who work with him. Don't knock your friends. Don't knock your enemies. Don't knock yourself.
You are not aware of the consequences that would result (if you were granted what you desire) because what you seek might be to your detriment. (O soul) be conscious that your Master is more aware about your well-being than you are.
