The Xiangâ€™er Precepts of the Dao are meant to summarize what the Daodejing says about appropriate conduct. They are held and regularly renewed by all Celestial Master (Tianshi) daoist priests. In a traditional daoist village lay people would also be encouraged to keep these precepts. The word translated here as "practice" is xing which actually means "a way of moving":
The Nine Practices
Practice lacking falseness.
Practice flexibility and weakness.
Practice maintaining the feminine. Do not initiate actions.
Practice lacking fame.
Practice clarity and stillness.
Practice good deeds.
Practice knowing how to cease with sufficiency.
Practice yielding to others.
Translated by Stephen R. Bokenkamp in, Early Daoist Scriptures.
The ninth precept, yielding to others, is wuwei. The first precept probably works better in English as "Be Honest." The second precept is often the tough one for people. The flexibility part sounds cool, but the weakness part is confusing. Here is what Wang Xiangzai says should be the second step of martial arts training:
If one does not have the basic mechanical ability, then no matter what the movement is like, it is all wrong. The same applies to using strength and not using strength. The movements of an ordinary person cannot have strength without constant unilateral tension that disturbs the blood circulation. Every kind of strength based on constant unilateral tension is stiff and inharmonious, and besides that, harmful to health. Having strength without constant unilateral tension is namely having strength without using strength, and when using it, one gains strength.
There is a type of strength that develops from fear of being weak. And there is a type of weakness that develops out of a fear of being too strong. The type of strength (shili) we are trying to reveal when we practice internal arts is potential strength--It can be cultivated while walking, sitting, reclining and standing still.
