四分律刪繁補闕行事鈔 2.164

2.164

貿寶戒十九。《多論》云：此以說淨寶，轉易與他求利，當與他時，得捨墮。此與貿衣五種不同，如《戒疏》說。律中以財物易錢寶故犯，但無衣食為異。五緣成：一是錢寶，二互相易，三決價，四為己，五受犯。《五分》：應對僧悔，不得向二三人前。律不犯中，若以錢貿瓔珞具，為佛法僧；若以錢易錢，亦為佛法僧者，得。

Precept nineteen on trading precious substances. The Sarvāstivāda-vinaya-vibhāṣā states: 'This means that by using precious substances that have been purified, one exchanges them with another to seek profit; at the very time of giving them to the other, one incurs a niḥsargika-pāyattika. This is different from the five ways of trading robes, as explained in the Precept Commentary.' In the Vinaya, trading property and goods for money and precious substances constitutes the offense; it differs only in not involving robes or food. Five conditions constitute it: first, it is money or precious substances; second, mutual exchange; third, fixing the price; fourth, for oneself; fifth, upon receiving it, the offense is committed. The Pañcavargika-vinaya states: 'One should confess before the saṃgha, not before two or three persons.' Among the non-offenses in the Vinaya: if one trades money for ornaments and implements for the sake of the Buddha, Dharma, or Saṃgha; or if one exchanges money for money, also for the sake of the Buddha, Dharma, or Saṃgha, it is permissible.
