Can you elaborate a bit on the traditional ways of demonstrating proficiency in say the Tibetan Lama Burning Palm?
Traditionally up to nine people could be lined up belly to back. The Tibetan Lama Burning Palm Master could selectively leave a complete handprint without hurting the individual on any one of the nine he chose with his intent. In modern times this is much too dangerous. The key I used at a demonstration was two thick phone books and a light slap. The lighter the slap and the clearer the entire hand mark the better. Dont try it!
