根本毗奈耶云。有苾芻二人。決擇義理。小者訶大者。大者遏入房中。瞋火所燒。尋即命終。身變為毒蛇。欲螫小者。時佛以大悲心。至其房。令小者懺悔。汝可作昔日苾芻想作禮。佛為蛇說法云。賢首。汝於我所。已修淨行。合生天上。由瞋火所燒。今作毒蛇。汝應知。諸行無常諸法無我。涅槃寂靜。蛇聞法已。即命終住天○瑞應經云。痛哉世間人。共爭不急事。於此極惡中。勤身苦營務。雖求不能得。徒役身心勞。死墮苦海中。自當無代者○南山鈔云。凡欲責他。先自量己內心喜怒。若有嫌恨。但自抑忍。火從內發。先自焚身。

The Mūlasarvāstivāda Vinaya says: 'There were two bhikṣus debating doctrines. The junior one reprimanded the senior one. The senior one held it in and entered his room; burned by the fire of anger, he immediately died. His body turned into a venomous snake wishing to bite the junior one. At that time, the Buddha, with great compassion, went to his room and had the junior one repent, saying: "You should visualize him as the bhikṣu of former days and pay homage." The Buddha preached the Dharma to the snake, saying: "Good friend, in my presence you once cultivated pure conduct and were destined to be born in heaven. Burned by the fire of anger, you have now become a venomous snake. You should know: all conditioned things are impermanent, all dharmas are without self, and nirvāṇa is tranquil peace." Having heard the Dharma, the snake immediately died and dwelt in heaven.' ○ The Ruiying Jing says: 'How painful are the people of the world! They fight together over unessential matters. In this extreme wickedness, they toil in body and undergo bitter strivings. Though they seek, they cannot obtain; in vain they wear out body and mind. At death they fall into an ocean of suffering, and naturally none will take their place.' ○ Daoxuan's Nanshan Commentary says: 'Whenever you wish to reprimand others, first weigh for yourself the pleasure and anger of your inner heart. If there is resentment, simply restrain and forbear yourself. If the fire erupts from within, it will first burn your own body.'
