Can emotion be controlled

Emotions can be controlled, although sometimes it can be difficult. People have more than one emotion at a time, so it may be that, let us say, you are very angry at someone and want to kill him, but you also love your wife, and you would not want to cause her the embarrassment of being married to a convicted murderer. There are innumerable other examples. Emotion is controlled by seeing your emotion in the larger context of your life, and all the other emotions that you also feel.
