Why healing is faster in nag but not in manav?

Why healing is faster in nag but not in manav, has anybady got any idea?

Yes this is true, yoga, meditatation, tai chi, chi gong and other forms of healing exercise works perfectly in manav but it takes long time. There was experiment of yoga carried out in the jails all over the world in different cultures and there were people who condemn it but had no choice struggle life or try. And result was extraordinary. Some of them who were grown up in a society, learnt only hate and revenge said today we saw there is something else in life as well.

In regard to healing faster in nag at will, probably it is possible. I don't know in physical level but there was an accident that caused this phenomena in mental level. I watched an amazing interview in discovery channel. An interviewee from America was telling, she went for rock climbing on her own. But unfortunately during climbing she fell down and broke her leg. Pain was in extreme level and there was no help at all. She somehow manage to call for help using her mobile. AS soon as call ended pain became so intolerable, she panicked and thought if ther is no pain , it would be so good.Surprisingly pain vanished. First she thought this is temporary and pain gradually came back. And then she started thinking from bottom of her heart,let this pain vanish, and it gradually vanished again. After that she maintained that state of mind. It took roughly 20 minutes of waiting for rescue helicopter to arrive. Until that time pain didn't comeback. But when rescue team put her inside the helicopter, she thought that now I am safe, as soon as she thought that Intolerable pain cameback. And she tried to do the same again, thinking not to have pain again. Unfortunately to her horror it didn't work this time. She tried again and again still it didn't work.
