四分律行事鈔資持記 2.823

2.823

四中，初明對易。相似謂以九物相易；不相似者，即互易；二種俱犯。若下，可捨物即已犯金寶，用此糴粟。以粟易物，雖復轉易，亦不合用。食但犯吉，異上《多論》。

In the fourth [part], first it clarifies reciprocal exchange: 'similar' refers to exchanging nine kinds of goods with each other; 'dissimilar' refers to mutual exchange; both kinds are offenses. From 'If' down, property that may be forfeited refers to already violated gold and treasure used to purchase grain; using this grain to exchange for goods, although converted and exchanged, is still not permissible for use. Consuming it incurs only a duṣkṛta, which differs from the *Sarvāstivāda Vinaya Vibhāṣā* above.
