四分律行事鈔資持記 2.1168

2.1168

四中，《十誦》。五塵不受，在文少漫，如注通之。《善見》，初明塵落。可決《十誦》。注中兩意，和會律論。嚮明，謂窓隙飛塵，細中復細者，則不須受。行下，次明食墮。亦約作意故成。《僧祇》，初簡諸塵。言作意者，塵飛入時，須起受意。乃下，明諸食，初明逆落成不。僧下，明不淨成受。僧尼宿觸，互望為淨。

In the fourth, in the Daśādhyāya-vinaya, "the five dusts are not received" is somewhat vague in the text, so the note resolves it. In the Samantapāsādikā, first dust falling is clarified, which can determine the Daśādhyāya-vinaya. The note contains two meanings, harmonizing the vinaya and treatise. "Facing the light" refers to airborne dust from window crevices, the finest of the fine, which then does not need to be received. "Falling..." onwards next clarifies falling food, which also relies on intentionality to be accomplished. In the Mahāsāṃghika-vinaya, first all types of dust are eliminated. "Intentionality" means that when the dust flies in, one must give rise to the intention to receive it. "Even..." onwards clarifies all foods: first clarifying whether falling in reverse order accomplishes it or not. "Sangha..." onwards clarifies that impure food accomplishes reception: overnight touch between monks and nuns is mutually considered pure.
