I had such high hopes for this thread. But I guess the answer to "what is ki" varies as much as do the various experiences that people have had.
Looks like there's just too much variation in what has been experienced (and what has not yet been experienced) for this to go anywhere.
You weren't seriously hoping for some kind of definitive consensus, were you? Just as well to expect a definitive answer out of a "discussion" of how many angels can dance on the head of a pin. A "discussion" on the meaning of "ki", IMO, primarily serves as entertainment for those who enjoy disputation that goes nowhere.
