Many men have a secret monster this way, a disease that they feed, a dragon that gnaws them, a despair that inhabits their night. Such a man seems like others, quite normal. Nobody knows that he has within him a fearful parasitic pain, with a thousand teeth, which lives in the miserable man, who is dying of it. Nobody knows that this man is a gulf. It is stagnant, but deep. From time to time a turmoil, of which we understand nothing, shows up on its surface. A mysterious wrinkle comes along, then vanishes, then reappears; an air bubble rises and bursts. It is a little thing, it is terrible. It is the breathing of the unknown monster.
