The forgiveness instructions in the article are very detailed and tie together many current popular ideas. Some people really like complicated systems, so maybe having so much to do helps them by crowding out the bad feelings that cause suffering. Another approach is to decide that being the judge is no longer your job, and to simply stop caring. It can be hard because caring about the injustice to done to you often reflects your best values: kindness, fairness, compassion. To turn off the judge in your brain can feel like you’re abandoning your values. But forgiveness is actually work, and you have to ask yourself if it’s one of those jobs that don’t really need to be done. So the trick is separate your values from the work of being the judge, and choosing to keep your values but let other people be the judge. This approach has helped me.
