Question 4:
Similar question for meridians ... How was their discovery found? Through someone attaining some enlightened state, and simply perceiving by intuition, and brain capacity, to be able to actually "know" the specific points? I myself have done some Qigong for some time, and I did begin to feel these "currents". But I didn't develop enough to really "know" as it appears here. But I did have a lot of intuitive ideas, concerning what I was able to "sense" and the reality of it all...
4). Answer:
I think it's a similar answer! Nowadays, small number scholars thought it's possible that the ancient traditional Chinese medical practitioners would see the meridians in their body or even in their patients body, but this view is not much accepted. It is still held that the discovery of the meridian-collateral system is the accumulation of the clinical practice and experience having handed down from generation to generation.
