According to our experience with anger, if you do not make an attempt to reduce it, it will remain with you and even increase. 

 Then even with small incidents you will immediately get angry.  Once you try to control or discipline your anger, then eventually even big events will not cause anger.Anger could be transformed into a positive emotion. For example, if one has a sincere compassionate motivation and concern for someone and that person does not heed one’s warning about his or her actions, then there is no alternative except the use of some kind of force to stop that person’s misdeeds.On the basis of compassionate motivation, anger may in some cases be useful because it gives us extra energy and enables us to act swiftly. 

 When anger comes, there is one important technique to help you keep your peace of mind.  You should not become dissatisfied or frustrated, because this is the cause of anger and hatred.  There is a natural connection between cause and effect… It is crucial to examine the situation so that at a very early stage one is able to put a stop to the causal process.  Then it does not continue to an advanced stage.Now you can see how to minimize anger and hatred.  First, it is extremely important to realize the negativeness of these emotions in general, particularly hatred.  I consider hatred to be the ultimate enemy.  By “enemy” I mean the person or factor which directly or indirectly destroys… happiness.

By using common sense, with the help of compassion and wisdom, I now have a more powerful argument with which to defeat anger.

~ The XIV Dalai Lama

I have learned through bitter experience the one supreme lesson to conserve my anger, and as heat conserved is transmuted into energy, even so our anger controlled can be transmuted into a power which can move the world.
