Virtue

And that virtue, O king, which tortureth one's own self and friends, is really no virtue. It is rather vice, producing calamities.

Virtue is sometimes also the weakness of men. And though such a man might ever be engaged in the practice of virtue, yet both virtue and profit forsake him, like pleasure and pain forsaking a person that is dead.

He that practiseth virtue for virtue's sake always suffereth. He can scarcely be called a wise man, for he knoweth not the purposes of virtue like a blind man incapable of perceiving the solar light.

He that regardeth his wealth to exist for himself alone, scarcely understandeth the purposes of wealth. He is really like a servant that tendeth kine in a forest. He again that pursueth wealth too much without pursuing virtue and enjoyments, deserveth to be censured and avoided by all men.
