Is there a difference in diagnosis and conditions? I like the Ba Gong methodology of “conditions” if that’s right. I see that the ancients weren’t looking into literal anatomy and “bugs” like in the west. But how was a disease described? I have read internal is more serious than external. And something can be both external and internal. Energy can come from the outside and lodge in organs and meridian can’t it? Through the “vents” I have read in places. The back of the neck, eyes, top of the head.
