Buddhist Yijing and arhat boxing are not as mysterious as the legend, but just exercises to keep fit. In addition, Tai Chi Chuan, Baduanjin, Wuqinxi, deep breathing, standing piles and other Taoist health preservation should be the most experienced. Practicing these does not violate the Buddha's beliefs. As long as you practice according to the teachings of Buddha and Bodhisattva, you are a good student of Buddha and Bodhisattva. Grandpa Dade also taught us to take good care of the fake shell of the body, otherwise we can't persist in spiritual achievements.
