四分律行事鈔資持記 2.1157

2.1157

護淨中，《僧祇》，初明過時。文中二罪，上是非時，下即停食。未過須臾，但犯非時；若過須臾，併結二墮。注中，初示時限。若下，明非時。二時者，一是過中，二過須臾。比丘下，次明淨手。為防宿膩。粗魯謂約略也。洗已更摩，謂後復相觸。而曾執物，容有不淨，故須更洗。注中準淨手以決觸巾。下引二律，轉證注文。律令盛食，明須淨者。《十誦》日洗，護淨可知。

In guarding purity, in the Mahāsāṃghika-vinaya, first it clarifies passing the time. In the text there are two offenses: the upper is improper time, and the lower is stopping food. If one has not exceeded a muhūrta, one commits only improper time; if one has exceeded a muhūrta, both pāyattikas are charged together. In the note, first it indicates the time limit. Below, from "If", it clarifies improper time. "Two times" means: first, passing noon; second, passing a muhūrta. Below, from "A bhikṣu", it next clarifies purifying the hands, in order to prevent overnight grease. "Rough and coarse" means casual. "Rubbing again after washing" means subsequently touching each other again. Moreover, having previously held substances, there could be impurity, so one must wash again. In the note, based on purifying the hands, touching a towel is decided. Below, two Vinayas are cited to further substantiate the text of the note. The Vinaya ordering food to be contained clearly requires it to be pure. The Daśādhyāya-vinaya's daily washing shows that guarding purity can be known.
