The Long Āgama Sūtra 17.19

17.19

「得安樂已，若有比丘說法，中有比丘作是言：『彼所說句正，義不正。』比丘聞已，不可言是，不可言非，當語彼比丘言：『云何，比丘！我義如是，汝義如是，何者為是？何者為非？』若彼報言：『我義如是，汝義如是，汝義亦勝。』彼比丘說此已，亦不得言是，亦不得言非。當諫彼比丘，當呵當止，當共推求，如是比丘盡共和合，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。

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

“A monk who hears him can’t say that he’s right or wrong. You should say to him, ‘How is it, monk? My meaning is this, and your meaning is that. Which is right, and which is wrong?’

“Suppose he replies, ‘My meaning is this, and your meaning is that. Your meaning is better.’

“When a monk says that, he can’t be said to be right or wrong. You should admonish, rebuke, and stop that monk. You should 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.
