四分律行事鈔資持記 3.914

3.914

十二，前明嚼楊枝，初出不嚼之過。癊，即痰癊。引，猶進也。《五分》，教洗棄。《四分》須屏處。大小二事，因而連引。次明經行，初顯益。一謂慣熟，二即專一，三謂血氣均和，四五可解。《十誦》示行相。晝地，謂作直道，不使斜曲故；或用磚石，為之。《寄歸傳》云：五天之地，道俗多作經行，直去直來，唯遵一路。（謂以磚石累為直道，狹而且長，人之往來，有同經緯，故以名焉。）又云：佛經行之基，闊二肘，長十四五肘。（闊三尺六，長二文六七許。）上以石作蓮華開勢，高二寸，闊一尺有十四五，表聖足迹也。《三千》中，明作處。隨處所宜，不可局故。

Twelfth: The former part explains chewing tooth-wood; first, it brings out the faults of not chewing. "Phlegm-fluid" (癊) refers to phlegm. "Lead to" (引) is like advancing. The Mahīśāsaka-vinaya teaches washing and discarding it. The Dharmaguptaka-vinaya requires a secluded place. The two matters of major and minor [defecation and urination] are brought in incidentally. Next, it explains walking meditation (caṅkramaṇa); first, it reveals the benefits. First, it brings familiarity; second, single-mindedness; third, blood and qi become balanced and harmonious; the fourth and fifth can be understood. The Daśādhyāya-vinaya shows the manner of walking. "Drawing the ground" means making a straight path, not letting it curve or bend; or one may use bricks and stones to make it. The *Nanhai jigui zhuan* says: In the land of the five Indias, both monastics and laity often practice walking meditation, walking straight back and forth, following only a single path. (This means stacking bricks and stones to form a straight path, narrow and long; people walking back and forth is similar to warp and weft, hence it is so named.) It also says: The base of the Buddha's walking meditation path was two cubits wide and fourteen or fifteen cubits long. (Three feet six inches wide, and about two zhang six or seven feet long.) Above, the stone was carved in the shape of blooming lotuses, two inches high and fourteen or fifteen inches wide, representing the marks of the Sage's feet. In the *Sanqian weiyi*, it explains the place where it is done: it depends on what is appropriate for the location and cannot be rigidly restricted.
