The rationale for loving others is the recognition of the simple fact that every living being has the same right to and the same desire for happiness, and not suffering, and the consideration that you as one individual are one life unit as compared with the mulititude of others in their ceaseless quest for happiness.
Dalai LamaHuman beings are not intrinsically selfish, which isolates us from others. We are essentially social animals who depend on others to meet our needs. We achieve happiness, prosperity and progress through social interaction. Therefore, having a kind and helpful attitude contributes to our own and others' happiness.
Dalai LamaIt is not enough simply to wish that love and compassion should increase in us. We need to make a sustained effort, again and again, to cultivate the positive aspects within us - and the key here is constant familiarity. The nature of human thoughts and emotions is such that the more you engage in them, the more you consciously develop them, the more powerful they become.
