四分比丘戒本疏 2.68

2.68

Thirty-seventh: The precept on eating at improper times. The Five Hundred Questions states: 'After midday, no material substance may enter the mouth. After eating, one should use a willow twig, or rinse the mouth with ashes; if not, one falls [into an offence].' According to this, in the preceding precept on sufficient food, after finishing eating, if one has altered one's bodily posture and not yet rinsed the mouth, with every swallow one commits [the offence of] sufficiency. If it enters past noon, with every swallow one incurs the offence of eating at an improper time.
