瑜伽論記 6.425

6.425

涅槃經中衣三食三處六為十二也，糞掃毳衣三衣名衣二，乞食一座一揣名食三，處同律解。智論衣二食五處五為十二，衣二者衲色，食五者一座中收，處五者除隨坐故。或有經說十六杜多，或有處說十一杜多，雖然多處說為十二。

In the *Nirvāṇa Sūtra*, three are for robes, three for food, and six for dwelling places, making twelve: refuse rag robes, woolen robes, and the three robes count as robes; begging alms, one sitting, and one measured portion count as three for food; the dwelling places are explained as in the Vinaya. In the *Mahāprajñāpāramitopadeśa*, two are for robes, five for food, and five for dwelling places, making twelve: the two for robes are patchwork robes and [plain] color; the five for food are subsumed under one sitting; the five dwelling places are because 'dwelling in whatever seat' is excluded. Some sūtras speak of sixteen *dhūtas*, and some places speak of eleven *dhūtas*, yet most places speak of twelve.
