1 Quiet sitting is sitting quietly. There is no method outside of this. This is not practicing Taiji [Taichi], which you do one set after another. You have to apply yourself to delving into stillness, and to feeling and experiencing it for yourself.
2 However, there is a key to this: “Be natural in everything. Put body and mind at ease. Do not try too hard. Do not force things, and definitely do not move qi deliberately.”
3 You must let things happen as they will, fitting in with natural laws that move the celestial bodies. It is like the movement of the sun and the moon. No power is propelling them along. This is why I say: “Being natural is the key to quiet sitting.”
