"Speaking of happiness and peace, what is the purpose of our existence in this world? Is it to find happiness? Or to experience suffering? Of course, most people would say, “Happiness!” In reality, how many people actually enjoy happiness and peace? What we hear and see most often are the wails of grief over the catastrophes of this world. These include natural disasters and man-made calamities such as war, violence, famine, poverty, and various stresses and anxieties experienced in everyday life. Very few people think of life as truly happy."
