When someone tries to intimidate you with their anger, they will continue to use it as long as it will work on you. How you react, how you think, how you feel when another uses anger, is the way to get beyond another’s anger.
If you have someone who is angry with you, don’t respond with anger as well. This is only creating more of an explosive vibration that amplifies. Do what you can to walk away from the anger. If you can’t physically, at least mentally. Stay centered and calm and rational. Then after the experience is over, do the inner work needed to release the anger that was attracted into your life.
