When you feel like saying something that you know you will regret, or keenly feel an insult not quite easy to forget, that's the time to curb resentment and maintain a mental peace. For when your mind is tranquil all your ill-thoughts simply cease. It is easy to be angry when defrauded or defied, to be peeved or disappointed if your wishes are denied: but to win a worthy battle over selfishness and spite, you must learn to keep strict silence though you know you're in the right. So keep your mental balance when confronted by a foe, be it enemy in ambush or some danger that you know. If you are poised and tranquil when all around is strife, be assured that you have mastered the most vital thing in life. Author Unknown
