An important point I like to make here is that regardless of what anyone's position on ki is, we are ALL just guessing because none of us know for sure what it is - the best we can do is come up with opinions that mean something to us personally that enables us to function in obtaining the true objectives of developing whatever skill it is that ki is supposed to be part of. As long as you keep focused on that, and are sure of what the results should be, you will be fine and it does not matter if you look at it as a western physics process, an eastern ki process, or some other wacky off-world Astral plane magic process - just as long as your personal model can produce the proper results.
The key of course is knowing what the proper results should be
