This video actually shows and infrared video of the masters hands during the demonstration, it's quite amazing, you cannot doubt the validity of this.
Well, I actually talked to someone who visited him. After the treatment the Master left the room, he tasted chamicals. At the next visit he brought his own towel, alu foil, but the Master would not prepare in front of him or do healing without the towel and foil. I don't know really what to think. This story comes from a Qi gong practicioner.
