妙法蓮華經玄贊 9.163

9.163

贊曰：釋身行。中有三：一標行處親近處；二別釋；三結之，於末後五句頌是也。或有經本為長行者，今取作頌，為正此標也。「處」謂處所，即前法也，三業諸行所依行處、可親近處。「行」謂遊息或復道理。如世說言：「汝向何處行在？」意言何道理中行在。其說經者，於一切時心常遊息此處所中，或安心神於是道理處所中故，故名行處。「親」謂親輔，「近」謂習近，「處」義同前。行者身心所應親輔，所習近處名親近處。行謂內所行，寢息身心行。親近謂外境，外緣所狹習。是此二種麁相差別。身行有親疎、有總別，獨名親近處；餘三不爾。但爾總得安樂行名。

The commentary says: Explaining the bodily practice. Within this there are three parts: first, stating the sphere of practice and the sphere of close association; second, explaining them separately; third, concluding it, which is the final five lines of verse. While some versions of the sūtra have prose, we now adopt the verse to confirm this statement. 'Sphere' (chù) means place, which is the aforementioned dharma; it is the sphere of practice and sphere of close association upon which all practices of the three karmas rely. 'Practice' (xíng) means wandering and resting, or again, principle. As people in the world say: 'In what place do you walk (xíng)?', meaning in what principle do you move? When the preacher of the sūtra at all times constantly lets his mind wander and rest in this place, or because he settles his spiritual faculties within the place of this principle, it is called the 'sphere of practice'. 'Close' (qīn) means intimate and supportive, 'association' (jìn) means familiarizing oneself, and 'sphere' (chù) has the same meaning as before. The sphere that the practitioner's body and mind should intimately support and become familiar with is called the 'sphere of close association'. Practice refers to what is practiced internally, the practice of resting body and mind. Close association refers to external objects, what is closely engaged through external conditions. This is the coarse distinction between the two. Bodily practice has intimacy and estrangement, generality and specificity, and thus alone is called the sphere of close association; the other three are not like this. They simply obtain the general name of peaceful practices.
