[1087] By a bhikkhu who enters the arena of contest (saṅgāmāvacara), when speaking in the Saṅgha, the matter (vatthu) should be known, the failure (vipatti) should be known, the offense (āpatti) should be known, the source (nidāna) should be known, the features (ākāra) should be known, what precedes and what follows should be known, what has been done and what has not been done should be known, the formal act (kamma) should be known, the legal issue (adhikaraṇa) should be known, the settlement (samatha) should be known; he should not go the wrong course of desire, he should not go the wrong course of hatred, he should not go the wrong course of delusion, he should not go the wrong course of fear; he should convince where convincing is fitting, he should cause reflection where causing reflection is fitting, he should look on where looking on is fitting, he should inspire confidence where inspiring confidence is fitting. Thinking, "I have gained a faction," he should not despise the other party; thinking, "I am of great learning," he should not despise one of little learning; thinking, "I am more senior," he should not despise one who is more junior. He should not speak on what has not come up; he should not let what has come up fall away from the Dhamma and from the Vinaya. By whatever Dhamma, by whatever Vinaya, by whatever instruction of the Teacher that legal issue is settled, in that way should that legal issue be settled.
