To control anger it is above all necessary
(1) to practice humility, because pride is always at the bottom of anger;
(2) to resist the first impulse to anger;
(3) to keep silence when provoked and resolve not to act on the spur of the moment;
(4) to remember that often no injury or insult was intended; (5) to consider the example of Jesus;
(6) to practice meekness;
(7) to think of the injury you do to yourself and the scandal you may give by anger;
(8) to combine the motives of reason and faith by keeping silence when angry, by offering the injury to God and suffering it in patience.
Then, thank God for the occasion of self-conquest and the victory, and pray for the one who has injured you.
–Peter Geierman (1870-1929)
