四分比丘戒本疏 2.63

2.63

問：若施衣時亦是一月五月者，與作衣時何別？答：時同義異，開二無失。作衣時者，元受衣時意為作衣，自後常有作衣之心，乃至衣上作馬齒縫即不失利。儻若中間作衣心斷，即失五利。施衣時者，無別要心，直受一月五月時利，是受施時，名施衣時。直至限滿，方失五利也。

Question: If 'the time of robe-giving' is also the one month or five months, how does it differ from 'the time of robe-making'? Answer: The periods are the same, but the meanings differ; allowing both involves no error. 'The time of robe-making' means that at the time one originally received the robe, the intention was to make a robe, and from then on one constantly maintains the intention to make a robe; even if one sews a 'horse-tooth' stitch on the robe, one does not forfeit the benefits. If halfway through the intention to make a robe is broken, one immediately forfeits the five benefits. 'The time of robe-giving' means that there is no specific intention; one directly receives the benefits of the one-month or five-month period. It is the time of receiving donations, so it is called 'the time of robe-giving'. Only when the time limit expires does one forfeit the five benefits.
