Compassion is defined in Buddhist teaching as the trembling or quivering of the heart in response to seeing pain or suffering. Alone with love and altruism, compassion can be seen as warm-heartedness replacing cynicism, beneficence taking the place of indifference, caring supplanting aloofness. The Dalai Lama, whose life has not been easy, has said, "The reason I am pretty happy is because of the force of compassion. Compassion makes me feel at one with everyone."
Thou hast given so much to me,
Give me one thing more – a grateful heart;
Not thankful when it pleaseth me,
As if Thy blessings had spare days;
But such a heart whose pulse may be
Thy praise.
