From the Dhammapada on Anger and Fault
Abandon anger, be done with conceit, get beyond every fetter.When for name and form you have no attachment — have nothing at all no sufferings, no stresses, invade.
When anger arises, whoever keeps firm control as if with a racing chariot: him I call a master charioteer. Anyone else, a rein-holder — that's all.
Conquer anger with lack of anger; bad, with good; stinginess, with a gift; a liar, with truth. By telling the truth; by not growing angry; by giving, when asked, no matter how little you have: by these three things you enter the presence of devas.
Gentle sages, constantly restrained in body, go to the unwavering state where, having gone, there's no grief.
Those who always stay wakeful, training by day and by night, keen on Unbinding: their effluents come to an end.
This has come down from old, Atula, and not just from today. Of the angry: they find fault with one who sits silent,
they find fault with one who speaks a great deal,
they find fault with one who measures his words.
There's no one unfaulted in the world. There never was, will be,
nor at present is found anyone entirely faulted or entirely praised.
