If a person holds a grudge, how will they feel when they find a grudge is being held against them?
To be forgiving doesn’t mean that you forget. But you reconcile with it. Your body manifests the experience in your gut or your throat and you get that “gut” feeling that tells you something isn’t right so you don’t make that mistake again. Or, your throat gets a lump and you know something is wrong. Your body is protecting you with your own experience and you become wiser, less prone to make the same mistakes.
If a person doesn’t forgive, how can they be forgiven?
You reap what you sow. Karma on steroids.
We can all choose to forgive. Forgiveness is the wise choice.
