Anger will never disappear so long as thoughts of resentment are cherished in the mind. Anger will disappear just as soon as thoughts of resentment are forgotten.
Holding on to anger is like grasping a hot coal with the intent of throwing it at someone else you are the one who gets burned.
You will not be punished for your anger, you will be punished by your anger.
In a controversy the instant we feel anger we have already ceased striving for the truth, and have begun striving for ourselves.
