Purchase a lock and key from a hardware store. On the lock print the word anger. To the key, attach the word control. Carry this lock and key with you when you think you may be getting into a situation that may tempt your temper. When the temptation to let out a burst of anger strikes you, pull out the lock and unlock it with your key. Imagine your anger being released without your having to say a word. Wait a few minutes and then lock it up again. View this as a spiritual practice. Imagine other ways in which you might use keys to lock and unlock other challenges in your life.
