In 1050 ACE, a monk traveled to the top of Mt Éméi, one of China’s Four Holy Mountains. This monk trained and meditated on Éméi and, when he realized liberation, took the name Báiyún (White Cloud). Chàn Master Báiyún Shŏuduān (白雲守) wrote all his sacred knowledge, including his system designed to cultivate health and treat illness while striving to attain enlightenment, in a book called “The Éméi Treasured Lotus Cannon” which is currently being held in a Beijing Museum.
