四分律行事鈔資持記 3.40

3.40

割截意中，初徵意。二引釋。《四分》不為賊剝者，以無所直故。《十誦》異外道者，彼著全段白㲲故。引律三賤，正取刀賤，人所棄故。已上諸意，皆託外緣，括其所歸，為破貪結，善巧之旨，其在茲乎！

Regarding the purpose of cutting and severing, first the purpose is queried. Second, citations explain it. In the Dharmaguptaka, it is so as not to be stripped by thieves, because it has no value. In the Daśādhyāya, it is to differ from non-Buddhists, because they wear whole lengths of white cotton. In citing the Vinaya's 'three cheap things', it precisely takes what is debased by the knife, because it is cast off by people. The above purposes are all reliant on external conditions; summarizing what they reduce to, it is to break the bonds of greed. Does not the purport of skillful means lie precisely here?
