One man finds nothing and nobody to believe or believe in, and so in his mind he remains alone.
Another man believes and believes in everyone and everything, taking all at face value and imbuing that superficial thing with his deepest soul – and so feels his soul stretched thin.
A third man lets all engulf him, wash over him, buffet him, and enter him – like water that he cannot embrace or reject – and then when he feels the temperature to be just right, he leaps wholeheartedly into the current to let it carry him onward.
