2.381

(According to the naiḥsargika-pāyattika offenses, there is a full set of eight grades of duṣkṛta. Two grades are root-derived, as listed below. Concealment comprises six grades in all: the first two grades of concealment arise from the root pāyattika; the middle two concealments arise from wearing or using the impure robes; the latter two concealments arise from remaining silent when the Saṃgha recites the precepts. All are reckoned by the passage of one night, two nights, and so on.)
