四分律行事鈔資持記 1.1132

1.1132

解界中。此章來意，為破古執以息後疑，非關夏限，故曰因明。以〈迦絺犍度〉中云：安居竟，有四事應作：自恣、應解界、應結界、應受功德衣；前引《母論》亦然；古師據比，故有妄釋。

In [the section on] dissolving the boundary: The purpose of this chapter is to refute old attachments so as to put an end to subsequent doubts; it is not concerned with the retreat limit, which is why it is called "clarified incidentally." Because the "Kaṭhina-khandhaka" states: "When the rains retreat is completed, four matters should be carried out: the pravāraṇā, dissolving the boundary, demarcating the boundary, and receiving the merit-robe (kaṭhina)"; and the Mother Treatise cited earlier also says this; ancient masters relied on this, and thus erroneous explanations arose.
