6B.15.  Mengzi said: When Heaven is about to confer a great responsibility on any man, it will exercise his mind with suffering, subject his sinews and bones to hard work, expose his body to hunger, put him to poverty, place obstacles in the paths of his deeds, so as to stimulate his mind, harden his nature, and improve wherever he is incompetent.

孟子曰：「 · · · 故天將降大任於是人也，必先苦其心志，勞其筋骨，餓其體膚，空乏其身，行拂亂其所為，所以動心忍性，曾益其所不能。 · · · 」
