In our concern for others, we worry less about ourselves. When we worry less about ourselves an experience of our own suffering is less intense. What does this tell us? Firstly, because our every action has a universal dimension, a potential impact on others' happiness, ethics are necessary as a means to ensure that we do not harm others. Secondly, it tells us that genuine happiness consists in those spiritual qualities of love, compassion, patience, tolerance and forgiveness and so on. For it is these which provide both for our happiness and others' happiness.
Dalai LamaThe ultimate source of a happy life is warm-heartedness. This means extending to others the kind of concern we have for ourselves. On a simple level we find that if we have a compassionate heart we naturally have more friends. And scientists today are discovering that while anger and hatred eat into our immune system, warm-heartedness and compassion are good for our health.
Dalai LamaHuman use, population, and technology have reached that certain stage where mother Earth no longer accepts our presence with silence.
