Reading this again, I do believe you are absolutely right, especially the perspective part. Also I believe it gets very hung up in the translation. It becomes some sort of mystical thing when to most CMA practitioners in China and TCM people in China is it very common and matter of fact. I believe Yang Jwing Ming associated with the endocrine system and I look at is as the electric current necessary for us to move. But it is not mystical, it is energy and it is neither created nor destroyed. And like I have said before; weak qi (out of balance) you are sick, strong qi (in balance) you are healthy, no qi (no energy left in the system) you are dead.
