Thanks, Basher. I've stumbled across some fascinating discussions about Charles Luk and Taoist Yoga, and I guess I'm not the only one intrigued and sometimes confused by his translation, as clear as it is. There's seems to be lots of different ways to explore internal alchemy here, and I'm still trying to figure out where to jump in. One thing that has really surprised me is that there seems to be people here who may have had similar experiences to mine. Years ago I had a remarkable and confusing kundalini experience - I guess it could be described as shaktipat, which was compelling enough to get my attention, to say the least. I've never actually met anyone who had the faintest idea what I was talking about when I mentioned having an orgasm that "didn't come out". I tried my best to have the experience more, but I found I couldn't make it happen. I've slowly learned more about kundalini and qi, but have been confused by much, too, and mostly have had to rely upon experimentation. I was attracted by microcosmic orbit meditation described by Mantak Chia as something similar to my experiences, but either I wasn't ready for it or key pieces seemed to be missing. The internal alchemy described by Charles Luk is like a pot of gold.
