If you don't know you don't need to know, right now. Its sorta a need to know type thing that has worked for centuries. If you are closed mind to to it telling you how it works or what it is will only cause a debate. Go see your western Doctors (they don't know everything), because you don't understand imbalances they can't find a cure then come back and ask after you studied more.

U can't teach Algerbra to 1st graders, when you are ready you will know.

I believe in Western Doctors too, but somethings you don't have to pay for, sometomes just studying and paying attention saves your health and money. Stress Kills Western Doctors know that.

Maybe someone else will explain it to you.
