I think it's like most things done well. As a musician, once you get good to the point of not thinking, one plays well. You play through the body, the feel; no thinking is in the way. same with pr. When we relax and let the body read, so to speak, it works. no trying, just do and let the body ,the feeling, do the work. I have recently experienced photo reading through the body when I kind of gave up and didn't try any more. It rather surprised me. you just suck in blocks of read. Just keep practicing without expecting results. But how do we get to that point of body feel ability? Make the goal the practice, not the results, than one day it kicks in. Hike
