The Long Āgama Sūtra 17.17

17.17

爾時，世尊告諸比丘：「我於是法躬自作證，謂四念處、四神足、四意斷、四禪、五根、五力、七覺意、賢聖八道，汝等盡共和合，勿生諍訟，同一師受，同一水乳；於如來正法，當自熾然，快得安樂。得安樂已，若有比丘說法中有作是言：『彼所說句不正，義理不正。』比丘聞已，不可言是，不可言非，當語彼比丘言：『云何，諸賢！我句如是，汝句如是；我義如是，汝義如是。何者為勝？何者為負？』若彼比丘報言：『我句如是，我義如是；汝句如是，汝義如是；汝句亦勝，汝義亦勝。』彼比丘說此，亦不得非，亦不得是。當諫彼比丘，當呵當止，當共推求，如是盡共和合，勿生諍訟，同一受，同一師，同一乳；於如來正法，當自熾然，快得安樂。

The Bhagavān then told the monks, “I’ve personally realized this teaching, namely the four abodes of mindfulness, four miraculous abilities, four mental disciplines, four dhyānas, five faculties, five powers, seven factors of awakening, and the noble eightfold path. All of you are united and don’t start disputes. You have the same teacher and teaching, the same water and milk. You must light yourselves with the Tathāgata’s correct teaching and delight in becoming peaceful.

“Once you’ve become peaceful, suppose some monk is teaching Dharma, and another says, ‘That statement isn’t correct, and his meaning isn’t correct.’

“A monk who hears him can’t say he’s right or wrong. He should say to that monk, ‘How is it, good man? I would say it this way, and you say it that way. My meaning is this, and your meaning is that. Which is better? Which is worse?’

“Suppose that monk replies, ‘I say it this way, and my meaning is this. You say it that way, and your meaning is that. Your statement is better, and your meaning is better, too.’

“The monk who says this also can’t be found to be right or wrong. You should admonish, rebuke, and stop that monk. You should then investigate the matter together. Thus, all of you will be united without starting disputes. You have the same teacher and teaching, the same water and milk. You should light yourselves with the correct teaching of the Tathāgata and delight in becoming peaceful.
