Hi, I was born in China, under communist rule, I did not understand or know the eptiomy of being Chinese, the Tao, the only recorded techniques to convert an every day Joe to a Taoist Immortal "shieh" or Godly Being. I read <Magus of Java> which really opened my eyes after seeing the youtube video John Chang. So I researched further into Taoism and WuDang. Does anyone have any information on the incredible "sleep meditation techniques"? I have the Nei Dan painting from Zhang Sanfeng and a book decoding the meaning of the painting. I am willing to share.
