[636] "The fool thinks he has won when he speaks harsh words; but victory indeed is his — the patient endurance (titikkhā) of one who understands. For him it thereby turns out worse — for the one who returns anger upon one who is angry; not returning anger upon the angry one, he wins a battle hard to win. He fares for the welfare of both — his own and the other's — who, knowing the other to be enraged, mindfully (sato) grows calm. While he is healing both — himself and the other — people think, 'He is a fool' — those who are unskilled in the Dhamma."
