I purchased the Spring Forest Qigong package. I recently have done some reserach on the internet and am finding information that Qigong is dangerous. That the breathing can be dangerous, and you can at times cause blockages or damaging outcomes that you definately do not want. The oppposite of what you are expeccting to happen. Also, that you should not try to learn on your own via, books, tapes, etc but only with an expert. I know you can always find the good and bad in anything and I don't believe everything I read on the internet, but wanted to hear people on the forums' feed back on this matter.
