四分律行事鈔資持記 2.1432

2.1432

初戒。（佛在舍衛，六群不齊整著內衣；居士譏言：如俳說人，如王大臣無異，故制。此篇百戒，多在舍衛，多因六群，下更不出；時有別者，隨為點之。）名云涅槃僧者，此云內衣，即是裙也。以西土裙法，橫疊圍身，長繩四繞，抽拔使正，多致不齊；此間作裙並連腰帶，但著有高下，亦違律制；當依《母論》踝上三指，即為齊整。

The First Precept. (The Buddha was in Śrāvastī. The group of six wore their undergarments unneatly; householders criticized them, saying: 'They are like comic performers, no different from kings and ministers,' so he laid down the prohibition. Of the hundred precepts in this chapter, most took place in Śrāvastī and were mostly due to the group of six, which will not be brought up below; when there are exceptions, they will be pointed out as they occur.) As for the name nivāsana, this translates as undergarment, which is the skirt. Since the skirt method in the Western lands is to wrap it around the body in horizontal folds, encircling it with a long cord four times and pulling it straight, it mostly results in unevenness. Here, skirts are made with attached waistbands, but wearing them high or low still violates the Vinaya prohibition; one should rely on the Mātṛkā: three finger-breadths above the ankle constitutes neatly arranged.
