||Duty must spring from the understanding; and the practices of those that are good should always be ascertained, O son of Kuru!
||The puissant Lord then created Truth, Duty, Penance, the eternal Vedas, all kinds of pious acts, and Purity, for enabling creatures to attain to heaven by practising them.
||Duty and its reverse, therefore, cannot be ascertained, O Bharata, by study of the scriptures alone
||Duty, however, is very subtile.
||Duty or religion is planted in his heart.
||The word Duty, as used in the Vedas, seems to have been coined in the first instance for general application so that it is applied to practices that have no merit in them.
||What indications has Religion or Duty been said to possess?
||How, indeed, do men become unacquainted with the details of Religion or Duty to succeed in observing them?
||Indeed, Religion or Duty has many branches all of which are fraught with happiness.
