瑜伽師地論略纂 8.79

8.79

論解十二杜多中，與《十二杜多經》似相違，來問。堪杜多，先云斗藪，斗藪塵垢也。　又云洗除身心也，亦云修治其心也。三衣，如前已釋。三安怛婆參者，安怛名內，婆參是衣，此衣通前二衣，應皆云三。

In the treatise's explanation of the twelve dhūtas, it seems to diverge from the *Twelve Dhūtas Sūtra*, which raises a question. *Dhūta* was formerly rendered as "shaking off"—shaking off dust and defilement. It is also said to wash and purge body and mind, or to cultivate and discipline one's mind. The three robes have been explained before. Regarding the three antarvāsas: *antar* means "inner," and *vāsa* means "robe"; this term applies across to the previous two robes, so all should be designated as three.
