“Reason gives each side time to plead; moreover, she herself demands adjournment, that she may have sufficient scope for the discovery of the truth; whereas anger is in a hurry: reason wishes to give a just decision; anger wishes its decision to be thought just. … The sword of justice is ill-placed in the hands of an angry man.” — Seneca
"You will not be punished for your anger, you will be punished by your anger." -Buddha
"Say to yourself at the start of the day, I shall meet with meddling, ungrateful, violent, treacherous, envious, and unsociable people. They are subject to all these defects because they have no knowledge of good and bad. But I, who have observed the nature of the good, and seen that it is the right; and of the bad, and seen that it is the wrong; and of the wrongdoer himself, and seen that his nature is akin to my own—not because he is of the same blood and seed, but because he shares as I do in mind and thus in a portion of the divine—I, then, can neither be harmed by these people, nor become angry with one who is akin to me, nor can I hate him, for we have come into being to work together, like feet, hands, eyelids, or the two rows of teeth in our upper and lower jaws. To work against one another is therefore contrary to nature; and to be angry with another person and turn away from him is surely to work against him." -Marcus Aurelius
