[55] Ānanda, there are these six roots of dispute (vivādamūla). What six? Here, Ānanda,
(1) a bhikkhu is angry (kodhana) and resentful (upanāhī). Ānanda, a bhikkhu who is angry and resentful dwells without respect and without deference toward the Teacher, dwells without respect and without deference toward the Dhamma, dwells without respect and without deference toward the Saṅgha, and does not fulfill the training (sikkhā). Ānanda, a bhikkhu who dwells without respect and without deference toward the Teacher, toward the Dhamma …, dwells without respect and without deference toward the Saṅgha, and does not fulfill the training, creates dispute in the Saṅgha—a dispute that is for the unwelfare of many people, for the unhappiness of many people, for the harm of many people, for the detriment and suffering (dukkha) of gods and humans. If, Ānanda, you should perceive such a root of dispute either internally or externally, then, Ānanda, you should strive in that case for the abandoning of that same evil root of dispute. And if, Ānanda, you should not perceive such a root of dispute either internally or externally, then, Ānanda, you should practice in that case so that that same evil root of dispute does not flow in in the future. Thus there is the abandoning of this evil root of dispute; thus there is the non-inflow of this evil root of dispute in the future.
