四分律行事鈔資持記 1.612

1.612

三五中。第三制親近者，先遠離故；律文上有應字。第四令遠離者，喜親近故。第五不應異語者，即九十中口綺。問：前後五種，未治得作，可得名奪；第三五過，及第四前三過，餘時並制，本不得作，何名奪耶？答：誠如來問，今望遮斷，前所喜犯，亦得名奪；但違行法，故異常犯。

Among the third five, regarding the third, prohibiting intimate association is because he must first stay far away; the Vinaya text has the character "should" (應) above it. The fourth, ordering him to stay far away, is because he is fond of intimate association. The fifth, not speaking differently, is frivolous speech among the ninety [pāyattikas]. Question: For the five kinds before and after, being able to do them when not under disciplinary treatment can be called 'curtailment'; but the third set of five faults, and the first three faults of the fourth set, are prohibited at other times as well and fundamentally must not be done, so why is it called 'curtailment'? Answer: It is truly as your question asks. Now, with a view to preventing and cutting off what he was previously fond of violating, it can also be called curtailment; however, because it violates the rules of disciplinary practice, it differs from ordinary offenses.
