My anger ends when I walk away from a person who is being unkind to me. So, Walk-Away Therapy is better than Forgiveness Therapy. Would you agree?
If the injustice is slight and short-lived, then walking away temporarily or even with an intent to reconnect with the person might be helpful. Yet, if the injustice is severe, then walking away tends to lead to the following: You walk away and have a temporary sense of relief. Yet, over time, the burden of carrying the effects of that injustice (frustration, resentment, and at times even hatred) is not left at the time and site of the injustice. Instead this excess emotional baggage can remain with you literally for decades. It is Forgiveness Therapy that can alleviate those burdens. Walking away under this circumstance means that you are walking with a sack of woes on your back.
