Friends are not causes of one’s happiness. Foes are not causes of one’s misery. Wisdom is not competent to bring an accession of wealth; nor wealth competent to bring an accession of happiness. Intelligence is not the cause of wealth, nor is stupidity the cause of extreme poverty. He only who is possessed of wisdom, and none else, understands the order of the world. Among the intelligent, the heroic, the foolish, the cowardly, the idiotic, the learned, the weak or the strong, happiness comes to him for whom it is ordained.
