第三解屈申中，謂於先往還覩瞻等時屈申手足臂及餘支節是其屈申。知屈申自相者，即是故意或是假人。知所屈申者，謂手足等。知時者，或須拍撝或為解勞等，餘時不應。若如是屈等者，知屈申意本為何事。

Third, explaining bending and stretching: bending and stretching the hands, feet, arms, and other limbs during the previous going, returning, looking, gazing, etc., is bending and stretching. Knowing the self-characteristic of bending and stretching refers to intentional action or conventional personhood. Knowing what is bent and stretched refers to the hands, feet, and so forth. Knowing the time means when clapping, waving, or relieving fatigue, etc., is required, whereas at other times one should not. 'If bent in such a manner', etc., means knowing what matter the intention of bending and stretching originally serves.
