瑜伽師地論略纂 8.80

8.80

Regarding the treatise mentioning "felt robe" (*cailaka*/*kambala*): fine hair is called *cui*; whether of birds or beasts, fine hair is called *cui*. Fearing that the three robes might be made of priceless fine cloth and the like, they are made of fine hair. The twelve dhūtas consist of: four for food, three for robes, and five for sitting. Here they are enumerated and differentiated into twelve in the explanation below, by separately dividing always sitting upright and sitting in the open place into two; these are merely the single practice of always sitting without lying down, as explained in the *Twelve Dhūtas Sūtra*. Although they are further differentiated below in eliminating hindrances and in the detailed explanation, they are still one despite separately eliminating hindrances.
