also, as another point of reference for the "whirling arms", Sat (Hon) also teaches a series of movements from some "pure" Tibetian "qigong" that he learned (while on retreat at Karma Choling, I believe), which are all of that nature, including a sequence of movements that are so similar to a series of moves in CTS's Gam Gong Man Gung set that it's just uncanny (I mean, I can't imagine the point at which those two disparate sources of practice must have diverged, so to have that particular series preserved to that degree is pretty remarkable)
kalaripayattu; I still remember back at NYU, some woman called me up when we first advertised for "the club" , claiming to have studied this, and was interested in demoing it; of course, at the time, I had never heard of it, so was probably more than a little dismissive (especially as she referred to it as "martial dance", which it is, to a large extent), so she never came down, but in retrospect, I kick myself for the missed opportunity, seeing as pretty much no one in NY teaches it, and there is a lot of very cool "lin gung" stuff in it;
