6.424

然此杜多名數開合不同，若依四分律，食四衣二處六合有十二。食四者，謂乞食，不作餘食，一座食，一揣食。衣二者，謂衲衣三衣，其次第乞乞食中收，過中不飲漿一坐中攝，處六如常解。

However, the enumeration and grouping of the names of these *dhūtas* vary. If one relies on the *Dharmaguptaka Vinaya*, four are for food, two for robes, and six for dwelling places, making twelve in total. The four for food are: begging alms, not eating food left over, eating at one sitting, and eating only one measured portion. The two for robes are: patchwork robes and the three robes; begging in succession is subsumed under begging alms, and not drinking porridge past noon is subsumed under [eating at] one sitting; the six dwelling places are as commonly explained.
