I agree with what Hope said, its not so much about a type of dubious "healing" so much as how its sold to people, using deception, group dynamics, etc.
But the ugly reality about "Pranic Healing" is that it is a quick way to make huge amounts of money, that is why they all make Big Claims. They claim big results, and charge big dollars, for what? Breathing, hand-waving?
It looks like Choa Kok Sui, one of the Guru's of PH is dead, and there is a lot of criticism of it out there. Choa Kok Sui died young at age 54, and was obese and in poor health...that is a clue.
