[188] Now on that occasion, a certain monk remembered an offense as the Pāṭimokkha was being recited. The thought occurred to him, “It has been laid down by the Blessed One that the Uposatha should not be performed by one with an offense. And I have fallen into an offense. What should I do?”
They reported the matter to the Blessed One.
“Monks, there is the case where a monk remembers an offense as the Pāṭimokkha is being recited.
“That monk should say to the monk next to him, ‘Friend, I have fallen into such-and-such offense. Having gotten up from here, I will make amends for the offense.’ Once that has been said, the Uposatha should be performed; the Pāṭimokkha should be listened to.
“Not from that cause alone should an obstruction to the Uposatha be made.
(Mv.II.27.5) “Monks, there is the case where a monk becomes doubtful about an offense as the Pāṭimokkha is being recited.
“That monk should say to the monk next to him, ‘Friend, I am doubtful about such-and-such offense. When I become free from doubt, then I will make amends for the offense.’ Once that has been said, the Uposatha should be performed; the Pāṭimokkha should be listened to.
“Not from that cause alone should an obstruction to the Uposatha be made.”
