As I have stated many times, there are mysteries that science is yet to crack. My personal opinion is that it is the power of the (possibly collective) intent or mind. PSacramento put it well, that he has had yrs of personal experience in martial arts. I too have witnessed masters perform physical feats that mere "training" could not provide.
Also the ancient Eastern cultures are still a mystery to most of the West. I can understand doubters, they simply have not had the passion and interest to search deeply. That's OK. For me, travelling to the Sub Continent and the East, not only freed me from the last of my jw indoctrination, it took me to the deepest darkest, terrifying places that finally cleared fears and psychological issues from my pained childhood.
Sadly there are many charlatans in the "alternative"healing world. I live in one of the leading centres on the planet, Byron Bay. I have been here 35yrs and in that time I have met possibly three people with the abilities that they DO NOT trumpet. It just shines out and they have assisted many to have their eyes opened.
There is so much more to write about but I guess I am preaching to the converted and pissing into the wind to the uninitiated....LOL!!
