In this world, all qualities spring from preferring the wellbeing of others to our own, whereas frustrations, confusion, and pain result from selfish attitudes. By adopting an altruistic outlook and by treating others in the way they deserve, our own happiness is assured as a byproduct. We should realize that self-centeredness is the source of all suffering, and that thinking of others is the source of all happiness.
