2.43

月望衣戒三　一制意。衣為資身隨時受用。雖先有衣故爛弊壞。但任受持不堪著用。今得少財為作三衣。以換故者而少不足為持滿。故聖開。一月過畜長貪違教妨道故。所以制墮　二釋名可知　三別緣有六。一若是新衣現堪受用。餘財不開故。衣方開故。第一緣故壞三衣。衣須故壞得財。若足亦受不開故。第二緣得少財不足。若不擬作三衣但犯。初戒不開。一月明須第三。為作三衣替故者。四不說淨作三衣。五無因緣。六過限便犯　闕緣比說。此戒因但三衣比丘開一月為限。若畜長衣者得即說淨。不須此戒。

The third precept: The month-long robe precept. 1. Purpose of institution: Robes are for supporting the body and are used according to need. Although one previously had robes, they have become worn out, tattered, and damaged; they can only serve to be formally received and kept, but are unfit to be worn. Now, having obtained a small amount of material to make the three robes, in order to replace the old ones, yet because it is a little insufficient to complete them, the Sage permitted an exception: one month. Since keeping an extra [robe] beyond this increases greed, contravenes the teaching, and obstructs the Path, for this reason he instituted [an offense of] falling. 2. Explanation of the name: Can be known. 3. Specific conditions: There are six: First, if it is new cloth, it must currently be fit for use; since other materials are not permitted, only cloth is permitted. This is the first condition: worn-out three robes. The robes must be worn out, and if one obtains enough material, it can be formally received and thus no exception is permitted. Second condition: obtaining a small amount of cloth that is insufficient. If one does not intend to make the three robes, it only constitutes an offense; the initial precept does not grant an exception. One month clearly requires the third: in order to make the three robes to replace the old ones. Fourth: not transferring it through spoken purification (vikappana) to make the three robes. Fifth: no mitigating circumstances. Sixth: as soon as the limit is exceeded, an offense is committed. Incomplete conditions: Can be known by comparison. This precept is granted as an exception with a one-month limit only for bhikṣus who possess [only] the three robes. If one keeps extra robes, as soon as one obtains them, one must perform spoken purification; this precept is not required.
