Hello from Alaska. I have the original VHS tape's of flying phoenix heavenly healing and have been doing this for quite some time. I just ordered the DVDs.
I am a Tlingit native in southeastern Alaska. There are various forms of qigong which are taught here Flying Phoenix Heavenly Healing has been the one I am familiar with most.
I originally bought the VHS tapes and years ago after I was diagnosed with rheumatoid arthritis.
When I first started, I actually found myself having so much energy that I found it rather difficult to go to sleep. Daily practice has made it so that my pain levels are next to zero. :-)
