四分律比丘戒本 1.p36

1.p36

Monks! thus have I repeated the thirteen Saṅghādisesa ordinances: the first nine (to be inflicted) for the first offence, the others after three warnings. If a monk have broken any one of the laws (above named), and wil fully concealed it, he ought to be placed under compulsory solitary confinement (pravāsa), after which he should pass six nights of mānatta penance. After this he ought to be absolved. Twenty monks in conclave may absolve him; if only one person short of twenty come together, he shall not be absolved; and in this case all the monks shall be considered blameworthy. This is the law. I now ask all the venerable ones in this assembly, are you pure or not (three times)? Venerable ones! this assembly is pure Silently therefore ye stand! So let it be.
