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 LamaMay I examine my mind in all actions and as soon as a negative state occurs, since it endangers myself and others, may I firmly face and avert it.
Dalai Lama
