I haven't read up on it, and my only exposure to it is a few people that say they believe in it. Correct my amateurish view of it, please.
Karma is the overriding force in the universe that keeps the good/evil scales in balance. If you do something rotten, you'll get something rotten back on you. If you do something good, you'll get something good in return.
An obvious hole in this idea is the people you can find that are basically creeps, but their lives go nicely. And likewise, the wonderful people you know whose lives are cruddy. One answer I have heard is that Karma keeps track, but doesn't keep individual lives in balance. For all the trouble you cause in this life, you'll be a worm, a bat, or a Jehovah's Witness in the next life -- that sort of thing.
All things considered, I can't see how the complicated mechanism of Karma differs from the simple random things that happen to people, coupled with the obvious idea that people will tend to be nice to you if you're nice to them.
I'm pretty convinced there's no life after death, and Karma doesn't seem to keep up over the course of a single lifetime, so I guess I'm a non-believer.
You?
