Saṅghasāmaggīsutta
“‘Saṅghasāmaggī, saṅghasāmaggī’ti, bhante, vuccati. Kittāvatā nu kho, bhante, saṅgho samaggo hotī”ti? “Idhupāli, bhikkhū adhammaṁ adhammoti dīpenti, dhammaṁ dhammoti dīpenti, avinayaṁ avinayoti dīpenti, vinayaṁ vinayoti dīpenti, abhāsitaṁ alapitaṁ tathāgatena abhāsitaṁ alapitaṁ tathāgatenāti dīpenti, bhāsitaṁ lapitaṁ tathāgatena bhāsitaṁ lapitaṁ tathāgatenāti dīpenti, anāciṇṇaṁ tathāgatena anāciṇṇaṁ tathāgatenāti dīpenti, āciṇṇaṁ tathāgatena āciṇṇaṁ tathāgatenāti dīpenti, apaññattaṁ tathāgatena apaññattaṁ tathāgatenāti dīpenti, paññattaṁ tathāgatena paññattaṁ tathāgatenāti dīpenti. Te imehi dasahi vatthūhi na avakassanti na apakassanti na āveni kammāni karonti na āveni pātimokkhaṁ uddisanti. Ettāvatā kho, upāli, saṅgho samaggo hotī”ti.
Harmony in the Saṅgha
“Sir, they speak of ‘harmony in the Saṅgha’. How is harmony in the Saṅgha defined?” “Upāli, it’s when a mendicant explains what is not the teaching as not the teaching, and what is the teaching as the teaching. They explain what is not the training as not the training, and what is the training as the training. They explain what was not spoken and stated by the Realized One as not spoken and stated by the Realized One, and what was spoken and stated by the Realized One as spoken and stated by the Realized One. They explain what was not practiced by the Realized One as not practiced by the Realized One, and what was practiced by the Realized One as practiced by the Realized One. They explain what was not prescribed by the Realized One as not prescribed by the Realized One, and what was prescribed by the Realized One as prescribed by the Realized One. On these ten grounds they don’t split off and go their own way. They don’t perform legal acts autonomously or recite the monastic code autonomously. That is how harmony in the Saṅgha is defined.”
