From 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
Dalai LamaPerhaps our teachings seem less religious and more technical, like psychology, so they are easier for secular people to use.
Dalai LamaHappiness arises as a result of different causes and conditions. If you harm someone out of anger, you may feel some superficial satisfaction, but deep down you know it was wrong. Your confidence will be undermined. However, if you have an altruistic attitude, you’ll feel comfortable and confident in the presence of others.
Dalai LamaThe very purpose of religion is to control yourself, not to criticize others. Rather, we must criticize ourselves. How much am I doing about my anger? About my attachment, about my hatred, about my pride, my jealousy? These are the things which we must check in daily life.
Dalai LamaMaterial progress and a higher standard of living bring us greater comfort and health, but do not lead to a transformation of the mind, which is the only thing capable of providing lasting peace. Profound happiness, unlike fleeting pleasures, is spiritual in nature. It depends on the happiness of others and it is based on love and affection.
