[36] "Venerable sir, it is said 'concord of the Saṅgha, concord of the Saṅgha (saṅghasāmaggī).' In what way, venerable sir, is a Saṅgha in concord?"
"Here, Upāli, bhikkhus explain what is not Dhamma as 'not Dhamma'; they explain what is Dhamma as 'Dhamma'; they explain what is not Vinaya as 'not Vinaya'; they explain what is Vinaya as 'Vinaya'; they explain what was not spoken and not uttered by the Tathāgata as 'not spoken and not uttered by the Tathāgata'; they explain what was spoken and uttered by the Tathāgata as 'spoken and uttered by the Tathāgata'; they explain what was not practised by the Tathāgata as 'not practised by the Tathāgata'; they explain what was practised by the Tathāgata as 'practised by the Tathāgata'; they explain what was not laid down (paññatta) by the Tathāgata as 'not laid down by the Tathāgata'; they explain what was laid down by the Tathāgata as 'laid down by the Tathāgata.' On these ten grounds they do not draw apart, they do not split away, they do not perform separate legal acts (āvenikakamma), and they do not recite the Pātimokkha separately. To this extent, Upāli, a Saṅgha is in concord."
