6.422

列名標數中，云如是依止若食乃至或十三種者，若依景師解：列名有十二攝為三類。食四衣三處中，有五總名敷具，處中第五常期端坐處如常坐也。若於次第乞食中分二：一、隨得乞食；二、巡家次第而乞，即有十三。若依乞食無差別性唯有十二：以隨得乞食總入次第乞食中收故。

Under listing the names and designating the numbers, where it says 'relying thus on food... up to thirteen kinds': if one relies on Master Jing's explanation, twelve are listed and subsumed under three classes. Four for food, three for robes, and among the dwelling places there are five, collectively termed bedding and sitting accessories (śayanāsana); the fifth among dwelling places is 'constant intention to sit upright' and 'dwelling in whatever seat one finds'. If within 'alms-begging in succession' one divides it into two—(1) begging alms as they are obtained, and (2) begging in order from house to house—then there are thirteen. If one relies on there being no distinction in the nature of begging alms, there are only twelve, because begging alms as they are obtained is entirely subsumed under begging alms in succession.
