梵網經古迹記 2.118

2.118

述曰：販賣有情他別為樂，市易棺材必求人死，下賤活命無過此焉。無罪命緣世間多有，故制菩薩犯即為罪。言「六畜」者，《周禮》云：牛、馬、犬、羊、豕、雞為六。理實通於一切畜生。「況教人作」者，以利他為最，故舉自況他。除下賤業，餘正販賣制道開俗。如《優婆塞戒經》云：在家人得財應作四分：一分供養父母妻子，二分如法販賣，餘一分藏積。

The Commentary states: To trade sentient beings, treating their separation as one's pleasure, or to traffic in coffins, necessarily wishing for people's deaths—no base livelihood surpasses these. Livelihood conditions that are without offense are plentiful in the world; therefore, the bodhisattva is prohibited from them, and an infraction constitutes an offense. Regarding the 'six domestic animals': the Rites of Zhou states that oxen, horses, dogs, sheep, pigs, and chickens constitute the six. In principle, this actually applies to all animals. Regarding 'how much less may one teach others to do so': since benefiting others is foremost, one's own action is mentioned to highlight that involving others [is even worse]. With the exception of base occupations, other proper commerce is prohibited for those of the path but permitted for the laity. As the Upāsakaśīla-sūtra states: when a layperson acquires wealth, they should divide it into four portions: one portion to support parents, wife, and children; two portions for lawful commerce; and the remaining one portion to store and accumulate.
