四分律行事鈔資持記 1.493

1.493

自然中，初明統通自然。即上剡浮一集，空即蘭若，有即聚落，水即水界，陸即道行；四種攝處，相無不盡。未分已前，通為一集。後下，明六相自然。即初開也。初三句敘緣開。隨境即上四處，分限即界量。人下，釋名。不假造作，故曰任運。言界起者，但是隨身到處，即有界限，非謂有法生起也。約下，指量。可知。

In the natural [boundary], it first explains the all-encompassing natural [boundary]. This is the single gathering of Jambudvīpa mentioned above: empty refers to araṇya, occupied refers to settlements, water refers to water boundaries, and land refers to traveling on paths; these four encompass all places, and their marks leave nothing out. Prior to delimitation, they collectively formed a single gathering. "After..." explains the six aspects of the natural [boundary], which is the initial concession. The first three lines recount the conditions for the concession. "Conforming to the environment" refers to the four places above; "demarcated limits" refers to boundary measurements. "Person..." explains the name. Because it does not rely on artificial formulation, it is termed "spontaneous." When it says "the boundary arises," it simply means that wherever the body goes, there are boundary limits; it does not mean that an actual dharma is produced and arises. "Restricting..." indicates the measurements, which can be known.
