“Bhante, it is said: ‘Concord in the Saṅgha, concord in the Saṅgha.’ How is there concord in the Saṅgha?”
“Here, Upāli, (1) bhikkhus explain non-Dhamma as non-Dhamma, and (2) Dhamma as Dhamma. (3) They explain non-discipline as non-discipline, and (4) discipline as discipline. (5) They explain what has not been stated and uttered by the Tathāgata as not having been stated and uttered by him, and (6) what has been stated and uttered by the Tathāgata as having been stated and uttered by him. (7) They explain what has not been practiced by the Tathāgata as not having been practiced by him, and (8) what has been practiced by the Tathāgata as having been practiced by him. (9) They explain what has not been prescribed by the Tathāgata as not having been prescribed by him, and (10) what has been prescribed by the Tathāgata as having been prescribed by him. On these ten grounds, they do not withdraw and go apart. They do not perform legal acts separately or recite the Pātimokkha separately. It is in this way, Upāli, that there is concord in the Saṅgha.” an.v.75
