Man feels helpless and lost: life loses meaning and taste; there is nothing to fill it with. He simply feels bad. Something uncertain “pulls” him. But where? Man doesn’t know where to turn, because the source of pleasure is concealed from him. Normally he chooses to forget all about it. In this respect, not a single suffering is lost, and will eventually lead, in some cycle of life in this world, to the realization of the necessity to turn to spiritual elevation in search of a salvation from suffering.
