四分律行事鈔資持記 2.1133

2.1133

列緣可知。若彼受食咽咽二俱墮。問：已有前制，理應不違；復開殘法，自可依作；如何受勸重興此戒？答：元彼懷恚，意欲令犯；強設巧言，誤令不覺；至論成犯，必與俱時；但所勸犯前，能勸犯後故。律中若彼棄之與人自作殘法等，則能勸但吉耳。

The enumerated conditions may be known. If the other receives the food, with each swallow both incur a pāyattika. Question: Since there was already the earlier prohibition, in principle one ought not to violate it; moreover, the leftover rite was permitted, so one could simply perform it accordingly; why, then, upon receiving an urge, was this precept instituted anew? Answer: Originally, the other harbored resentment and intended to cause him to commit an offense; he cleverly contrived artful words to mislead him without his realizing it. When it comes to constituting an offense, they must occur at the same time; yet the one urged violates the earlier rule, while the one urging violates the latter rule. In the Vinaya, if the other discards it, gives it to someone else, or performs the leftover rite himself, then the one urging commits only a duṣkṛta.
