菩薩戒義疏 2.28

2.28

第十二、販賣戒。希利損物，乖慈故制。大小同犯，七眾不全共。夫販賣者，謂生口、六畜，或販賣良人，多有眷屬分張之苦。若販賣棺材，則惡心希售，故道俗俱斷。若自作，若教他為我，或教他自作，悉犯輕垢。若偷販生口，賣畜生令殺，呪令人死，欲得棺材售，此別犯盜罪、殺罪。

Twelfth, the precept against trading: it is established because seeking profit harms living beings and contravenes compassion. The Great and Small [Vehicles] commit the offense alike; the seven assemblies do not entirely share it. Trading refers to [trafficking in] slaves or the six domestic animals, or trading in freeborn people, which mostly entails the suffering of separation of kin. In trading coffins, an evil mind hopes for sales, so it is severed for both monastics and laypeople. If one does it oneself, or instructs another to do it for oneself, or instructs another to do it for themselves, in all cases one commits a minor defilement infraction. If one steals and traffics in human beings, sells animals so they will be slaughtered, or uses curses to make people die in order to sell coffins, these separately commit offenses of theft and murder.
