It is always surprising to me when someone wishes bad Karma on someone else. I have a few friends who do this regularly. Whenever one feels slighted or tries to comfort someone else that feels hurt, they will try to invoke Karma with "That's ok. Karma will get them"; or "Hurry up, Karma."
It's like they have hired the universe's hitman to swoop down and seek exacting revenge, and it can't happen fast enough.
I understand. Sometimes people get hurt, feel betrayed, or get angry. They feel bad and want the person who did them wrong to feel bad. They are seeking revenge but don't want the guilt.
They expect the universe to reach out and do it for them. Otherwise, they may feel wrong about hurting the other person. Wishing bad Karma is the new passive-aggressive revenge.
Wishing bad Karma on someone has nothing to do with Karma in the traditional sense. The word has is misused. In this context, the concept evolved to mean revenge. Hoping Karma "gets someone" is wishing something negative happens to them. Can anything positive come out of that?
We have choices in our lives. We can focus on things that are positive or negative. It is easy to hope someone suffers because they have hurt you, but is that really what you want?
Seeking revenge, whether passive or active, is a hollow and short-lived victory. There is nothing good or positive that can come of it. As Gandhi said, "An eye for an eye only ends up making the whole world blind."
Wishing for something negative to happen or focusing on the negative creates more negativity. Instead, wish for something positive. Hope the person who hurt you (or someone else) realizes the error of their ways.
Forgiving isn't always easy, but it allows for a better chance at true happiness.
