Busyness of city is just a distraction from self, a palliative measure, not a solution or cure from such mental diseases, which are nothing more than our Author's calls to the conscious life. The more a person distances himself, ignores these calls, the more painful their hunt will be to him.
"People are looking for pleasures, throwing themselves from side to side, because they feel the emptiness of their lives." (Blaise Pascal)
"Dead are those who, immersed into transient and carnal cares, do not even know that they have a soul, which demands its liberation, and of that to live means to fight, means to die, that only this way can the great liberation be achieved." (de Lamennais)
The solution is only in one: in living simpler, and taking time to ponder about the meaning of human life. For that, the writings by Leo Tolstoy are priceless:
