四分比丘戒本疏 2.16

2.16

Eighth: the precept against urging an increase upon hearing that a single household wishes to make an offering, causing them to buy fine robes. Ancient authorities called this the precept against urging and praising a single householder to increase the robe's price; its meaning was largely obscured. The text has four clauses: first, allowing for the perpetrator; second, having fixed a price limit with the intention of buying for the monk; third, "this monk, not having previously been invited by the donor to ask freely, nevertheless urges an increase"; the Vinaya says, "If one increases by a single thread, or increases by one-sixteenth of a coin, it is an offence in all cases." Fourth: specifying the offence of obtaining the robe.
