釋禪波羅蜜次第法門 2.117

2.117

第三、調身；第四、調息；第五、調心。此應合用，不得別說，但有初、中、後方法不同，是則入住出相有異。

Third, harmonizing the body; fourth, harmonizing the breath; fifth, harmonizing the mind. These should be applied together and cannot be treated separately; there are only differences in the methods for the beginning, middle, and end, which are the different characteristics of entering, abiding in, and emerging [from concentration].
