Agreed I don't fully understand the Buddhist and Hindu meanings of Karma, but I like to think of it in a much larger context than what goes around comes around, or if you do bad, bad stuff will happen to you etc. I think of it more in terms of what you put out in the world goes into the cycle. Not physical cause and effect as much as bad feeds bad, good feeds good. It's the whole Yin Yyang thing, this constant cycle two parts of the same whole, constantly at odds, and yet depending upon each other for their mutual existence, and as each pushes against the other they keep the cycle going. Of course characterising Yin and Yang as "good and bad" is part of the western misunderstanding. Especially to think of them as either or, as opposed to parts of the same whole.
