Kural - 701

Who knows the sign, and reads unuttered thought, the gem is he,
Of earth round traversed by the changeless sea

The minister who by looking (at the king) understands his mind without being told (of it), will be a perpetual ornament to the world which is surrounded by a never-drying sea.
