Mahavagga, Khandaka 4, Chapters 6-13

7.1. At that time there assembled in a certain residence (or district) on the day of Pavāraṇā a number of resident Bhikkhus, five or more. They did not know that there were other resident Bhikkhus absent. Intending to act according to Dhamma and Vinaya, thinking themselves to be complete while (really) incomplete, they held Pavāraṇā. While they were holding Pavāraṇā, other resident Bhikkhus, a greater number (than the first ones), arrived.

They told this thing to the Blessed One.

2. 'In case there assemble, O Bhikkhus, in a certain residence on the day of Pavāraṇā (&c., as in § 1, down to) they hold Pavāraṇā. While they are holding Pavāraṇā, other resident Bhikkhus, a greater number, arrive. Let (all) those Bhikkhus, O Bhikkhus, hold Pavāraṇā again; they who have held Pavāraṇā, are free from guilt

3. 'In case there assemble, &c. While they are holding Pavāraṇā, other resident Bhikkhus, exactly the same number (as the first ones), arrive. Those who have held Pavāraṇā, have held it correctly; let the other ones hold Pavāraṇā; they who have held Pavāraṇā, are free from guilt.'

Note: The following paragraphs and chapters exactly follow the course indicated by II, 28-35. The alterations to be made are obvious and sufficiently indicated by §§ 1-3; instead of, 'Let them proclaim their Pārisuddhi ' (II, 28, 4, &c.), read here, 'Let them pronounce their Pavāraṇā.'
