3.17-19 Yas ca etc.  upto purusah.  However, for a person who rejoices in the Self and performs action simply as a [routine]  business of organs of action,  there is no difference between  (his) action and nonaciton.  That is why he inflicts  punishment on, or does favour to, every being,  not with desire for any gain for himself,  but with a conviction that it a is thing that deserves to be performed.  Therefore, just  unattached, one should perform action that  is to be performed.
