I have been engaging in relaxation training to overcome my anger toward a family member. It seems to be working, but at times my anger wells up and makes me uncomfortable. My question is this: Is relaxation training sufficient or not to overcoming anger?
Relaxation training may be sufficient if the injustice you experienced is not severe. If, on the other hand, it was a severe injustice, then relaxation by itself may only quell symptoms and not be a cure for your resentment. Resentment, or deep and abiding anger, is not necessarily cured by relaxing because, once you are finished relaxing, the anger can return. When you forgive, the resentment can be cured.
