四分律行事鈔資持記 3.781

3.781

十一中，《十誦》，初教善說。諸法實相，言通大小；且據小教，即指偏空。此下，令訶止。當觀是非，勿隨好惡。又下，聽演布。但不違義，隨意廣張；述義可爾，臨文不聽；由是聖勅，不雜凡言。（今有麁心，輒注聖典；準此例決，過非輕細。）《五分》。受施，先無意故。《十誦》。說時不得食者，不諦受故。

In the eleventh section: In the Daśādhyāya-vinaya, it first instructs on speaking skillfully. The "true nature of all phenomena" in phrasing applies to both Mahāyāna and Hīnayāna; but relying for now on the Hīnayāna teaching, it refers to one-sided emptiness. From "This [way]..." down, it orders reproving and stopping [them]. One must observe right and wrong, and not follow [personal] likes and dislikes. From "Also..." down, it allows expounding broadly. Provided it does not go against the meaning, one may expand it as one wishes. Expressing the meaning is permissible, but facing the text it is not permitted; this is because it is a holy decree, not to be mixed with ordinary words. (Nowadays there are crude-minded people who rashly write commentaries on the holy scriptures; judging by this precedent, their fault is by no means light or trivial.) In the Mahīśāsaka-vinaya: One accepts the donation because there was originally no intention. In the Daśādhyāya-vinaya: The reason one must not eat while preaching is that one would not be receiving attentively.
