They think, ‘It’s allowable for us to do the observance-day ceremony; it’s not unallowable.’ Being anxious, they do the observance-day ceremony and recite the Monastic Code. When they’ve just finished … When they’ve just finished, and none of the gathering has left … When they’ve just finished, and only some members of the gathering have left … When they’ve just finished, and the entire gathering has left, a greater number of resident monks arrive … an equal number of resident monks arrive … a smaller number of resident monks arrive. In such a case, what has been recited is valid, and the late arrivals should announce their purity in the presence of the others. There’s an offense of wrong conduct for the reciters.”
