Needless to say, the traditional Chinese Ch’an Buddhist – Master Xu Yun – had no formal or informal ties or connections to Japanese Zen Buddhism, and never practised (or advocated others to practice) a Japanese Zen that does not follow the Vinaya Disciple, and which deviates from established Ch’an practice.
The Chan doctrine of the Mind was handed down through Mahakasyapa and his successors in India and reached China where it was eventually transmitted to Master Hui-neng, its Sixth (Chinese) Patriarch. This was the Transmission of the Right Dharma which then flourished (all over China).
Immoral behaviour is a physical manifestation of immoral psychological patterns operating in the mind, and its presence serves as a permanent ‘block’ to any advancement toward enlightenment.
The maintaining of physical discipline in the Buddhist sense, is a form of what is known in China today as ‘qigong’ (氣功), or to use the much older name – ‘daoyin’ (導引). Qigong is the cultivation of inner energy (qi) through directed willpower and effort (gong), whilst daoyin is the practice of ‘directing’ and ‘leading’ (dao) inner energy (qi), whilst ‘yin’ is the wilful process of ‘pulling’ the inner energy (qi) through the body and causing it to flow to all areas without hindrance.
Then Mahakasyapa transmitted to him the Tathagata’s Mind Seal, making him the second Indian Patriarch. The transmission was handed down to following generations, and after the Patriarchs Asvaghosa and Nagarjuna, Chan Master Hui-wen of Tian-tai Mountain in the Bei-qi Dynasty (550-78) after reading (Nagarjuna’s) Madhyamika Shastra, succeeded in realizing his own mind and founded the Tian-tai School.269 At the time, our Chan Sect was very flourishing.
