Hi everyone, this is my first post here. I want to share a very interesting book that I read recently. It's called China's Super Psychics, written by Paul Dong. Not sure whether you guys have heard of it or not. The author is a Qigong master himself, in this book he tells some really interesting stories about the Qigong fever in China in the 1980s. In one chapter, he even introduces a way to open "heavenly eyes", he says most people can achieve this with 4 months' practice. I'm impressed by one of the conclusions in the book, ie. Qigong practice has a strong relation to ESP abilities. The healing power of Qi is also real. He also mentions "bi gu" (Chinese fasting), it's basically an advanced form of Qigong. Basically, human beings can survive on Qi by practicing Qigong. I know some theories in Daoism also prove this.
I'm still learning about these subjects and doing some research in my free time. Btw, I find this website has some instructional books on Qigong that seem legit. Also, here's an interesting released document on Qigong.
I'm very happy to find this great forum. Hope to make some friends here!
