I believe in karma. I have for as long as I can remember. I think that's a good thing. It helps dictate my actions every day.
Whenever my mind starts toying with the idea of doing something devious, I stop the thoughts dead in their tracks and project to the future. I think to myself: If I go ahead and do this, which does not represent my better self, what are the repercussions? It helps maintain my dignity.
My father would call it acting with integrity, which he did very well by the way. But I like to put a more mystical spin on it. Just think, if we all strived for better karma, the world would probably be in a much better place.
In fact, it's not a bad idea to look back at where you screwed up and fix it in the present. Perhaps you will prevent some bad karma that's heading your way from come at you to bite you in the butt.
Of course, you have to wonder why some people that exude pure goodness keep getting faced with one tragedy or another. I think it's because their ancestors had bad karma and they are the ones that are paying for it. For example, everyone talks about the Kennedy curse. The patriarch of the family, Joe Kennedy, was a bootlegger and as crooked as they come. Now the whole clan has had to pay for his dirty deeds.
It's a far-fetched theory, I know. But for some of us, it's the only way we can make sense out of the world. And really, is that such a bad thing? It's better to try to do good things in the name of karma, then not try at all.
