四分律刪繁補闕行事鈔 3.29

3.29

六堤數長短。《四分》文不了。五條七條，具明定量長短，大衣準同。《婆論》云：大衣，下者兩長一短，中者三長一短，上者四長一短，名如法作；若互增減，成受持，著用得罪。所以須割截者，《四分》云：不為怨賊所剝。《十誦》：與外道異故。律中沙門衣三種賤：一刀賤（謂割壞故），二色賤（不正色染），三體賤（謂糞掃世棄者）。

6. The number of panels and their lengths. The text of the Dharmaguptaka Vinaya is unclear. For the five-strip and seven-strip robes, it clearly specifies the fixed lengths, and the great robe is analogous. The Sarvāstivāda-vinaya-vibhāṣā states: "For the great robe, the lower has two long and one short [panel per strip], the medium has three long and one short, and the upper has four long and one short; this is called making it in accordance with the Dharma. If one interchanges or alters their numbers, taking and keeping it is still valid, but wearing and using it incurs an offense." The reason why it must be cut into pieces: The Dharmaguptaka Vinaya states: "So that it is not stripped by robbers and thieves." The Daśādhyāya-vinaya states: "To distinguish it from the tīrthikas." In the Vinaya, the śramaṇa's robe has three kinds of lowliness: first, lowliness of the knife (meaning cut and ruined); second, lowliness of color (dyed with an improper color); third, lowliness of material (meaning picked from refuse and discarded by the world).
