Lack of understanding of the true nature of happiness, it seems to me, is the principal reason why people inflict sufferings on others. They think either that the other's pain may somehow be a cause of happiness for themselves or that their own happiness is more important, regardless of what pain it may cause. But this is shortsighted. No one truly benefits from causing harm to another sentient being. . . . . In the long run causing others misery and infringing their rights to peace and happiness result in anxiety, fear, and suspicion within oneself.
Dalai LamaEven more important than the warmth and affection we receive, is the warmth and affection we give. It is by giving warmth and affection, by having a genuine sense of concern for others, in other words through compassion, that we gain the conditions for genuine happiness. More important than being loved, therefore, is to love.
Dalai LamaWhen the days become longer and there is more sunshine, the grass becomes fresh and, consequently, we feel very happy. On the other hand, in autumn, one leaf falls down and another leaf falls down. The beautiful plants become as if dead and we do not feel very happy. Why? I think it is because deep down our human nature likes construction, and does not like destruction. Naturally, every action which is destructive is against human nature. Constructiveness is the human way. Therefore, I think that in terms of basic human feeling, violence is not good. Non-violence is the only way.
