Why do so many people have a problem with this? As I see it you have 2 ways to live your life. You can be a glass-half-empty kind of person or a glass-half full kind of person. The choice (and this is the key) is yours and yours alone.
If you want to go through life always angry, scheming out ways to get even with folks or in general lugging around what used a chip on your shoulder that has over time turned into a something much heavier and more burdensome to your life. Simply stated, you do not forgive for someone else, you forgive for yourself. You forgive person X for whatever slight that happened years ago and what happens? You have freed yourself of a negative burden, and it feels good. So good it is time to dump some more rubbish on the highway of your life. (just be careful to not get a ticket for littering).
Some bags may be quite large, some quite small. Just dump the trash like you dump your household trash every week. Why burden yourself with the negativity? It can be something as silly as a network killing off your favorite character on a favorite show of yours or as deep and complex as years of lies from a parent. Can anything good come out of the anger over those things? When you forgive, you do not change the past but you do present an opportunity for new doors and paths to appear in the future. Don't forget to forgive yourself as well. Most of us have a conscience, and we occasionally do things we regret and so must live with a guilty conscience. Forgive yourself. Apologize for the transgression - put It behind both of you. You'll be glad you did.
Do not go through life unnecessarily burdening yourself. Use the tools available to us all in our life kits - those kits are there for a reason,
That's my shack-take on this weeks topic. See ya next week when once again Ramana and I tackle the same topic.
