Maxim 

  When a sage comes in contact with fools, he must not expect to be

honoured, and if an ignorant man overcomes a sage in an oratorical

contest, it is no wonder, because even a stone breaks a jewel.

        What wonder is there that the song

        Of a nightingale ceases when imprisoned with a crow

        Or that a virtuous man under the tyranny of vagabonds

        Feels affliction in his heart and is irate.

        Although a base stone may break a golden vase,

        The price of the stone is not enhanced nor of the gold lost.
