四交貿中有五，初二句以八易衣。犯販賣故。以下四句，以衣易八。得寶即犯貿寶。綿毺俗邊犯販賣。若以下四句，上明二自相貿。衣易衣犯販賣，寶易寶犯貿寶。下明以二貿六，得輕，可知。六下四句，六種自貿。或對貿，或互易，並吉。又以六易二，販貿二墮，準上可明。此下，點上販賣，對人輕重。上云犯捨，且據俗論。

In the fourth section, on trading, there are five parts: The first two lines concern exchanging robes for the eight [kinds of precious items], which incurs the offense of selling. The following four lines concern exchanging robes for the eight [kinds of items]; obtaining precious substances immediately incurs the offense of trading precious substances; [exchanging] raw cotton or rugs with householders incurs the offense of selling. The following four lines from 'if' downward explain trading the two [types of heavy items] among themselves: exchanging robes for robes incurs the offense of selling; exchanging precious substances for precious substances incurs the offense of trading precious substances. Below, it explains using the two to trade for the six; that one incurs a light [offense] can be known. The four lines from 'six' downward concern the six kinds traded among themselves: whether trading like for like or exchanging mutually, all are duṣkṛta.
