I’ve posted my response (which ended up being pretty long :)), on my blog here.

Whew! I’m glad my post generated some discussion. I just got back from vacation, and am looking forward to reading through your dissection here (may take me a few days, have a lot to do now that I’m back). In that essay, I tried approaching karma in a very non-traditional manner, rarely using traditional formulations and explanations. And I purposefully avoided the metaphysical multiple-lives aspects of karma, that are definitely present in true Buddhist karma. I was viewing it strictly from a “this-life” perspective, and my thought is that while that sort of view may not be complete, it is practical and effective, and often easier to “use” than multi-life karma. I’ll comment further as I read through your post here.

Okay…. so the subject line “Is Karma Messing Up Your Dharma?” may be too cute! But can you ask yourself this question seriously? The concept of Dharma is that we are driven by a spiritual force deep within our souls……

“When this is not, that is not;
This ceasing, that ceases.”

The stoic argument about heaps — the sorites paradox that no one specifiable grain in a pile of wheat makes the heap, — makes that case at about the same time, I’m guessing, that causal issues were being discussed in Buddhism. I’m sure that the Buddhists, who were terrifically hairsplitting causuists, had got there first. But what did they say about such cases?
