Mbh 12.259.2a

"'Bhishma said, "The practices of the good, the Smritis, and the Vedas, are the three indications (sources) of righteousness. Besides these, the learned have declared that the purpose (for which an act is accomplished) is the fourth indication of righteousness.[1116] The Rishis of old have declared what acts are righteous and also classified them as superior or inferior in point of merit. The rules of righteousness have been laid down for the conduct of the affairs of the world. In both the worlds, that is, here and hereafter, righteousness produces happiness as its fruits. A sinful person unable to acquire merit by subtile ways, becomes stained with sin only. Some are of opinion that sinful persons can never be cleansed of their sins. In seasons of distress, a person by even speaking an untruth acquires the merit of speaking the truth, even as a person who accomplishes an unrighteous act acquires by that very means the merit of having done a righteous act. Conduct is the refuge of righteousness. Thou shouldst know what righteousness is, aided by conduct.[1117] (It is the nature of man that he neither sees nor proclaims his own faults but notices and proclaims those of others). The very thief, stealing what belongs to others, spends the produce of his theft in acts of apparent virtue. During a time of anarchy, the thief takes great pleasure in appropriating what belongs to others. When others, however, rob him of what he has acquired by robbery, he then wishes forthwith for a king (for invoking punishment on the head of the offenders). At even such a time, when his indignation for offended rights of property is at its highest, he secretly covets the wealth of those that are contented with their own. Fearlessly and without a doubt in his mind (when he is himself the victim of a robbery) he repairs to the king's palace with a mind cleansed of every sin. Within even his own heart he does not see the stain of any evil act.[1118] To speak the truth is meritorious.
