If we adopt a self-centered approach to life, by which we attempt to use others for our own self interest, we might be able to gain temporary benefits, but in the long run we will not succeed in achieving even our personal happiness, and hope for the next life is out of the question.
Dalai LamaThe key to genuine happiness is in our hands. To think this way is to discover the essential values of kindness, brotherly love and altruism. The more clearly we see the benefits of these values, the more we will seek to reject anything that opposes them; in this way we will be able to bring about inner transformation.
Dalai Lama
