We need to find secular ways to cultivate warm-heartedness. We need secular ways to educate ourselves about inner values. The source of a happy life is within us. Trouble makers in many parts of the world are often quite well educated, so it is not just education that we need. We need to pay attention to inner values.
We 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.
Compassion suits our physical condition, whereas anger, fear and distrust are harmful to our well-being. Therefore, just as we learn the importance of physical hygiene to physical health, to ensure healthy minds, we need to learn some kind of emotional hygiene.
It is in everybody's interest to seek those [actions] that lead to happiness and avoid those which lead to suffering. And because our interests are inextricably linked, we are compelled to accept ethics as the indispensable interface between my desire to be happy and yours.
