A tip for taming anger

I remember reading somewhere that customer service desks often times have a mirror mounted behind them so that customers can keep their cool when complaining. I thought of that when I read this quote from by Thich Nhat Hanh from Taming the Tiger Within: Meditations on Transforming Difficult Emotions:

Whenever anger comes up, take out a mirror and look at yourself. When you are angry, you are not very beautiful, you are not presentable. Hundreds of muscles on your face become very tense. Your face looks like a bomb ready to explode.

I don’t really pull out a mirror, but when I begin to feel my face get tense I immediately remind myself to relax my jaw and muscles and it helps to temper the hot emotions. — CD
