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 LamaThe most important benefit of patience consists in the way it acts as a powerful antidote to the affliction of anger - the greatest threat to our inner peace, and therefore our happiness. The mind, or spirit, is not physical, it cannot be touched or harmed directly. Only negative thoughts and emotions can harm it. Therefore, only the corresponding positive quality can protect it.
Dalai LamaWe cannot hope to die peacefully if our lives have been full of violence, or if our minds have mostly been agitated by emotions like anger, attachment, or fear. So if we wish to die well, we must learn how to live well: Hoping for a peaceful death, we must cultivate peace in our mind, and in our way of life.
Dalai LamaWe are beset by problems and if we look for their source, we find they arise because of our selfishness, because we tend to pursue our own interests at the expense of others. Our various religious traditions exist to help us reduce these problems. They all teach ways to overcome suffering through cultivating love and compassion, tolerance, patience and contentment.
