Hey Dave,
When I was first out of the organization, I went to a presentation on Buddhism - incidentally, it took place across the street from the Kingdom Hall on a meeting night - and the lecturer spent a good deal of time talking about Karma. I wrote up some notes about it when I got home that evening, in my personal journal. Obviously, I'm no expert, but this is what I got out of the presentation:
Buddhism says that there are seven streams of pain in the world:
1. Birth
2. Aging
3. Sickness
4. Death
5. The fact that we have to confront situations we would rather not.
6. The fact that situations we enjoy end.
7. The fact that it is impossible to fully satiate our desires.
Karma says that every action or thought we have sows a seed – either a positive seed or a negative one. The seeds will eventually find expression when the external conditions are ripe. For example, having angry feelings sows seeds of anger, even if they are not expressed at the moment. When external conditions appear that are conducive to expressing the anger, it will be expressed.
Bad karma has four negative consequences:
1. Maturation result (negative karma going forward)
2. The result corresponding to the initial act (hitting someone produces the likelihood of receiving similar treatment yourself).
3. The result corresponding to the initial experience (hitting someone makes it more likely that you will hit someone again).
4. Environmental results (hitting someone means you must now live in a world where people hit each other).
Of these, the worst is considered the third, because it means that doing something bad makes it more likely that you will do something bad again, creating a cycle of bad karma.
Like many of the others on this thread, I find the concept of Karma to be appealing in some ways, but in my mind, the problem with the definition that goes beyond normal cause-and-effect is that it requires some kind of universal score-keeper, which I don't think exists. Also, the idea that everyone really gets their just desserts in the next life sounds a whole lot like a cop-out invented to handle the reality that people don't always get their just desserts in this life. In other words, creative license to make the philosophy work.
I believe in a brand of Karma that is strictly down-to-earth. People who are open and honest are likely to see and take advantage of opportunities to improve themselves, be good neighbors and citizens, find satisfying work, and so on. People who are dishonest and unsavory will tend to push others away, limiting their enjoyment of human relationships and life. But this kind of cause-and-effect is so straightforrward that it hardly bears having a special name. It would be easier to just call it "the way things are."
Just some ramblings.
