Mat,

I'm no expert in Qigong but I think your setting yourself up. I don't know you so I don't know what's going on in your life, but you seem to be having a very strong reaction to a very common occurance. Try, 'thanks Master Lin for making me aware of the sharp angry energy occurning outside of my awareness and manifesting on the physical level'. I bet that with a little time and patience you'll see that you got infinitly more healing than you bargained for. Looking forward to hearing about it.
