《善見》中，初句標示。彼下，引別文。為餘事者，彼釋盜戒聚蘭分齊，非衣界故。諸師下，定量。十三步，計七丈八尺。即以下，明諸界通塞。問：作法所以不通者？答：《戒疏》有三釋：一有法故無，無法故有。二自然內外俱是無法，作法內是有法，外則無法。三自然是本制故開，作法是開，故不復開。

In the Samantapāsādikā: the opening sentence indicates the heading. "That..." below cites another text: "for other matters" refers to that [text's] explanation of the delimitations of settlements and araṇyas for the precept against stealing, not the robe boundary. "The various masters..." below determines the measurement: thirteen paces equals seven zhàng, eight chǐ. "That is..." below clarifies the openness and obstruction of the various boundaries. Question: Why is it that boundaries established by legal procedure do not allow [an influential perimeter]? Answer: The Precept Commentary has three explanations: First, because there is an established procedure, it lacks [an influential perimeter]; because there is no established procedure, it has it. Second, in a natural boundary, both inside and outside lack established procedure; in a boundary established by legal procedure, the inside has established procedure, while the outside lacks established procedure. Third, a natural boundary is an original restriction and thus an exception is opened; a boundary established by legal procedure is already an exception, so it is not opened further.
