先須識息有四伴：有聲曰風，守之則散；結滯曰氣，守之則結；出入不盡曰喘，守之則勞；不聲、不滯，出入俱盡曰息，守之則定。當求靜處結跏，平身正直，縱任身體，散誕四支，布置骨解。當令關節相應，不倚不曲。緩帶，轉側調適，以左手置右手上，大指纔令相詣。縱放頰車，小小開口，四、五過長吐氣。次漸平頭，徐徐閉目，勿令眼臉太急，常使籠籠，然後用息也。

First, one must recognize that breath has four companions: that with sound is called wind—attending to it leads to dispersal; that which is blocked and stagnant is called qì—attending to it leads to blockage; that which exits and enters incompletely is called panting—attending to it leads to exhaustion; that which is without sound and without stagnation, exiting and entering completely, is called breath—attending to it leads to samādhi. One should seek a quiet place, sit cross-legged, straighten the body upright, relax the physical frame, loosely stretch the four limbs, and align the bones and joints. One should ensure that the joints correspond, neither leaning nor bent. Loosen the belt, adjust oneself by shifting, place the left hand upon the right hand, with the thumbs just touching. Relax the jaws, slightly open the mouth, and exhale deeply four or five times. Next, gradually level the head, slowly close the eyes without letting the eyelids be too tight, always keeping them relaxed and hooded, and only then use the breath.
