四分律行事鈔資持記 1.523

1.523

定初始中，初示法。東南為始，且據此方門多南向；餘向隨改，不必一定；若約通論，不問方隅；但從寺門左角發首，可為定準。相當者，始末還合也。律下，遮濫。恐執律文，妨行事故。以起方則四維不分，起維則方維俱顯；又方面通漫，起無所從故也。

In [the section on] determining the starting point: first, it indicates the method. Taking the southeast as the start tentatively relies upon gates in this land mostly facing south; when other directions are faced, it is adjusted accordingly and is not necessarily fixed. If we take the general view, regardless of the cardinal direction or corner, starting from the left corner of the monastery gate can serve as a fixed standard. "Mutually corresponding" means that the start and end reunite. From "the Vinaya..." onward, it prevents mistakes, for fear that clinging to the Vinaya text might obstruct the transactions. This is because if one starts from a cardinal direction, the four intermediate directions are not distinguished, but if one starts from an intermediate direction, both cardinal and intermediate directions are made clear; moreover, the cardinal directions are broad and indistinct, so there is nowhere to initiate [the boundary].
