Stored anger is a problem

The storing up of anger, which is resentment, requires the antidote of forgiveness; but the storing up of anger is far more significant than forgiveness. Forgiveness is unnecessary when there is no accumulation of anger. Forgiveness is essential if there is resentment; but to be free from flattery and from the sense of injury, without the hardness of interference, makes for mercy, charity. Anger cannot be got rid of by the action of will, for will is part of violence. Will is the outcome of desire, the craving to be; and desire in its very nature is aggressive, dominant. To supress anger by the exertion of will is to transfer anger to a different level, giving it a a different name; but it is still part of violence. To be free from violence, which is not the cultivation of non-violence, there must be the understanding of desire.
