迦絺那衣法（《明了論》翻為堅實也！能感多衣，衣無敗壞；又名難活，以貧人取活為難，捨少財入此衣，功德勝如以須彌大衣聚施也！或云堅固；或名廕覆；古翻為賞善罰惡衣，賞前安居人，後安居不得也！亦名功德衣，以僧眾同受此衣，便招五利功德也！）

The Procedure of the Kaṭhina Robe
(The Vinayavibhāṣā translates it as "firm and solid": it can attract many robes, and the robes do not spoil. It is also called "difficult livelihood," because for poor people making a living is difficult, and renouncing even a small possession toward this robe brings merit surpassing the offering of a mountain-sized pile of robes as huge as Sumeru. Some also call it "firm"; some name it "sheltering cover"; an old translation calls it the "robe that rewards good and punishes evil," rewarding those of the early varṣā, while those of the late varṣā do not obtain it. It is also called the "merit robe," because when the community of the saṃgha jointly receives this robe, it brings about the merits of five privileges.)
