The ability to remain at peace when you do not get what you want is forgiveness….
When you want something different from what you actually get, you are always in a position of struggle. That struggle often shows up as anger or despair or a sense of helplessness. The good news is that you can get over those negative emotional reactions and learn to be at peace….
Whether or not you remain at peace is mostly up to you. Forgiveness contains the understanding that another person’s action, no matter how awful, does not compel you to be endlessly miserable, angry, or emotionally distraught.
