In order to feel purposeful in one’s life, one must believe that there is more to existence than depleting ones time. Fulfillment is a by-product of having a sense of purpose. The following quote recognizes that there is more to existence than just living.
“If there were no eternal consciousness in a man, if at the foundation of all there lay only a wildly seething power which writhing with obscure passions produced everything that is great and everything that is insignificant, if a bottomless void never satiated lay hidden beneath all–what then would life be but despair? If such were the case, if there
were no sacred bond which united mankind, if one generation arose after another like the leafage in the forest, if the one generation replaced the other like the song of birds in the forest, if the human race passed through the world as the ship goes through the sea, like the wind through the desert, a thoughtless and fruitless activity, if an eternal oblivion were always lurking hungrily for its prey and there was no power strong enough to wrest it from its maw–how empty then and comfortless life would be!”
