We consider that the lives of all beings are just as precious as our own, and through this we develop a sense of concern for others.
Dalai LamaIf 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.
Dalai Lama
