I was not at all refering to that discussion, but to the question of the origin of the qi concept. I thought I had made that clear.
Stefan, I'm not sure if you're aware of it, but there is a valid body of thought that the idea of ki came from the early explanations of how the body moves. I.e., that discussion I just pointed out has a very great deal to do (potentially) with the "origin of the qi concept". The human body is thought to be a reflection of how the universe works... and vice versa. Think about that and which theory came first. No one knows for sure. But I think we can assume that it would be odd if the actual movement of the human body coincidentally conformed with some disparate view of how the cosmos works, right?
