Thus if a man faces adversities, pain and torments in this world and is overtaken therein by waves of calamities and tribulations, he will inevitably come to resent it. His attachment to it will diminish and he will come to distrust it. If he believed in another world, a vast world free of every kind of pain and grief, he will inevitably want to migrate to it, and if he were unable to make the journey physically, he will send his heart out to it.
