We try to evade the question of existence with property, prestige, power, possession, production, fun, and, ultimately, by trying to forget that we- that I- exist. No matter how much he thinks of God or goes to church, or how much he believes in religious ideas , if he, the whole man, is deaf to the question of existence, if he does not have an answer to it, he is marking time, and he lives and dies like one of the million things he produces. He thinks of God, instead of experiencing God.
