The following Mindfulness writing by Thich Nhat Hanh is a beautiful application of mindfulness for help with anger...
The first function of mindfulness is to recognize, not to fight. "Breathing in, I know that anger has manifested in me. Hello, my little anger." And breathing out, "I will take good care of you."
Once we have recognized our anger, we embrace it. This is the second function of mindfulness and it is a very pleasant practice. Instead of fighting, we are taking good care of our emotion. If you know how to embrace your anger, something will change.
It is like cooking potatoes. You cover the pot and then the water will begin to boil. You must keep the stove on for at least twenty minutes for the potatoes to cook. Your anger is a kind of potato and you cannot eat a raw potato.
Mindfulness is like the fire cooking the potatoes of anger. The first few minutes of recognizing and embracing your anger with tenderness can bring results. You get some relief. Anger is still there, but you do not suffer so much anymore, because you know how to take care of your baby. So the third function of mindfulness is soothing, relieving. Anger is there, but it is being taken care of. The situation is no longer in chaos, with the crying baby left all alone. The mother is there to take care of the baby and the situation is under control.
