When you become aware of your anger, you are no longer angry.
Fear, anger, envy, sadness - they are like a ringing phone. Once you pick up the phone - once you get the message - the phone stops ringing.
But we, as silly humans, often stand there staring at the phone, immersed in the discomfort of its annoying ring, and we let it ring, and ring, and ring...
Pick up the phone!
(unless, of course, it's joy - then let it ring!)
