The best way to control sudden outbursts of emotion is by developing the habit of exercising the willpower suddenly, promptly. If you return anger or jealousy or hatred or prejudice or any other bitterness, you only keep the flame of that emotion alight. It is just the same as when one keeps love alive in another's heart by adding a little affection and love all the time. If you withhold it it will die, for there is nothing to stimulate it. When a person is always offended, or when he dislikes this or that, he is keeping the fire going, whereas once you pass it by and smile you raise yourself above it and it will die out, for then it has no more food to live on.
