Bhishma said, It is by conduct that one acquires longevity, and it is by conduct that one acquires wealth and prosperity. Indeed, it is by conduct that one acquires the fame that rests upon great achievements both here and hereafter. A man whose conduct is improper or wicked never acquires a long life. All creatures become afraid of such a man and are oppressed by him. If, therefore, one wishes one's own advancement and prosperity, one should, in this world, betake to conduct that is proper and good.
Good conduct succeeds in dispelling the inauspiciousness and misery of every one that is sinful.
Righteousness has conduct for its indication. They that are good and righteous are so in consequence of the conduct they follow. The indications, again, of good conduct are afforded by the acts of those that are good or righteous. People esteem that man who acts righteously and who does good acts even if they only hear of him without actually seeing him. They that are atheists, they that are destitute of all acts, they that are disobedient to preceptors and transgress the injunctions of the scriptures, they that are unacquainted with and therefore, unobservant of duties, and they that are wicked of conduct, become shortlived .
