The Wisdom of Dao Yin in Baopuzi

Dao Yin treats the condition ‘not yet sick’, it releases inharmonious energy. The movements must be practised in order to circulate energy without discomfort in the hundred joints. Without movement, blood remains blocked in the three places. Dao Yin uses this great rule to maintain health and is a subtle and complex technique for eliminating all diseases.
