律戒本疏 1.40

1.40

十九銀買種種物　言種種物則是一切所須之物也。大比丘用捨墮。金銀隨意所買。若法非法無不備有。因是結戒。悉不聽也。凡捨墮物之所買。盡是捨墮物也。唯可食物貪欲得突吉羅。無可捨故。無漸故。其過甚重。要僧中懺悔然後乃除耳。

Nineteenth: Buying various goods with silver. The expression "various goods" means all necessary articles. A great monk uses a niḥsargika-pāyattika [matter], buying whatever he pleases with gold and silver; whether lawful or unlawful, everything is provided. On this account, the precept was formulated, completely disallowing it. In general, whatever is bought with niḥsargika-pāyattika goods is entirely niḥsargika-pāyattika goods. Only for edible things, greedily obtaining them incurs a duṣkṛta, because there is nothing to forfeit. Because of shamelessness, its fault is exceedingly heavy; one must repent in the Saṃgha, and only then is it cleared.
