Anger cannot be overcome by anger. If someone is angry with you, and you show anger in return, the result is a disaster. On the other hand, if you control your anger and show its opposite - love, compassion, tolerance and patience - not only will you remain peaceful, but the other person's anger will also diminish.
If indeed the qualities such as love, patience, tolerance, and forgiveness are what happiness consists in, and if it is also true that compassion, defined as concern for others, is both the source and the fruit of these qualities, then the more we are compassionate, the more we provide for our own happiness.
unless the direction of science is guided by a consciously ethical motivation, especially compassion, its effects may fail to bring benefit. They may indeed cause great harm.
For an act to be moral the intention must be based on compassion, not duty. We do something because we want to do it, because we feel we have to do it, not because we ought to do it. And even if our efforts fail - or we never even get to implement them - we are still moral because our motivation was based on compassion.
What acts as a far more effective circumstance for generating compassion and what, in fact, rouses us from our comfortable meditation seat is actually seeing or hearing others - encountering others directly, not just conceptually in our imagination.
The compassion we feel normally is biased and mixed with attachment. Genuine compassion flows towards all living beings, particularly your enemies. If I try to develop compassion towards my enemy, it may not benefit him directly, he may not even be aware of it. But it will immediately benefit me by calming my mind. On the other hand, if I dwell on how awful everything is, I immediately lose my peace of mind.
It is not enough to be compassionate. You must act. There are two aspects to action. One is to overcome the distortions and afflictions of your own mind, that is, in terms of calming and eventually dispelling anger. This is action out of compassion. The other is more social, more public. When something needs to be done in the world to rectify the wrongs, if one is really concerned with benefitting others, one needs to be engaged, involved.
We are all, by nature, clearly oriented toward the basic human values of love and compassion. We all prefer the love of others to their hatred. We all prefer others’ generosity to meanness. And who is there among us who does not prefer tolerance, respect and forgiveness of our failings to bigotry, disrespect, and resentment?
