Posted this on another forum, just thought I would put it up here too. Tibetans seem to have their own Qi Gong too?? Not too sure, but there seems to be a lot of "internal" stuff going on, such as the way the yogis generate tremendous heat in their bodies. There was some interesting research about this by academics, I will see if I can find the link. Hope this is ok to post here, I believe it to be related to "internal" practice. It is well worth a watch if you have the time.
