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.
Dalai LamaEven more important than the warmth and affection we receive, is the warmth and affection we give. It is by giving warmth and affection, by having a genuine sense of concern for others, in other words through compassion, that we gain the conditions for genuine happiness. More important than being loved, therefore, is to love.
Dalai LamaFrom the scientific view, the theory of karma may be a metaphysical assumption -- but it is no more so than the assumption that all of life is material and originated out of pure chance
