四分比丘戒本疏 2.19

2.19

第十一、乞野蠶綿自作臥具戒。准律緣起，損命招譏而制也。言臥具者，古來相傳南山律師等並云是三衣也；淨三藏云即是氈蓐之類也。今詳，即是此方臥帔也。故黑毛臥具戒開文云「作蓐作氈，不犯」。既云臥具，故知是帔。若言是三衣者，如減六年不捨故者作新便犯，豈可三衣要捨故者方得作新。一月衣戒續辦新財，豈須捨故？故《多論》名為敷具，淨三藏亦名敷具者，或可部別、或可上敷下敷皆名敷具，通論是帔也。又以臥帔亦堪持作三衣，諸教故有濫也。又臥帔資要，故應有此諸制法也。此戒害命，若犯捨者律令斬壞，不同餘戒。

Eleventh: the precept against soliciting wild silk floss to make a rug for oneself. According to the origin story in the Vinaya, it was instituted because of harming life and inviting censure. As for "sleeping gear" (rug), ancient tradition, Vinaya Master Nanshan, and others all said it refers to the three robes; Tripiṭaka Master Yijing said it refers to mats, cushions, and the like. In my present examination, it is the sleeping quilt (pei) of this land. Therefore, the exemption clause in the precept on black wool rugs states: "Making a mattress or making a felt rug incurs no offence." Since it is called "sleeping gear," we know it is a quilt. If one says it refers to the three robes, just as with the precept against making a new one within less than six years without giving up the old, one would commit an offence upon making a new one; how could it be that with the three robes one must give up the old before being permitted to make a new one? And in the one-month robe precept, when seeking new material, must one give up the old? Therefore the Sarvāstivāda-śāstra calls it a "spread" (āstaraṇa), and Tripiṭaka Master Yijing also calls it a "spread"; this might be due to differing schools, or both what is spread above and spread below are called spreads—generally speaking, it is a quilt. Moreover, because a sleeping quilt can also be formally resolved and used as the three robes, there is confusion in the various teachings. Furthermore, because a sleeping quilt is an essential requisite, there ought to be these various regulations. This precept involves harming life, so if one commits an offence and forfeits it, the Vinaya requires it to be cut up and destroyed, unlike other precepts.
