Minor nitpick - kamma and karma are the same thing, but different languages. Kamma is Pali and karma is Sanskrit.

To be even more detailed, karma is the action rather than the effect, which is called karma vipaka. The English word karma means something more fluid - depending on context.

Thanks, I do know but in general English speakers use the word karma and then ascribe the Hindu reading to Buddhism, so I was answering that.

As to the cause and effect part, again, I wasn't about to start on a "there are no causes and no effects, only conditions…" path as it would only muddy the water for the person I'm responding to, but I don't mind the nitpicking, it's a good point and glad to see reasonable challenges in the comments.

Edit, I didn't mean to put this all on the English!
