[429] While he was observing mānatta, he fell in the interim into one offence (āpatti)—intentional emission of semen (sañcetanikā sukkavisaṭṭhi)—concealed for five days. He informed the bhikkhus: "Friends, I fell into one offence, intentional emission of semen, concealed for a fortnight … While observing mānatta, I fell in the interim into one offence, intentional emission of semen, concealed for five days. How now should I proceed?" Those bhikkhus reported this matter to the Blessed One. "Well then, bhikkhus, let the Saṅgha, having sent the bhikkhu Udāyi back to the beginning on account of the one offence fallen into in the interim—intentional emission of semen, concealed for five days—and having granted combined probation (samodhānaparivāsa) together with the earlier offence, grant six nights' mānatta."
