न मे पार्थास्ति कर्तव्यं त्रिषु लोकेषु किञ्चन।
नानवाप्तमवाप्तव्यं वर्त एव च कर्मणि।।3.22।।
3.22. O son of Prtha ! For Me, in the three worlds there is nothing that must be done; nor is there any thing unattained [so far] to be attained; and yet I exert in action.
3.21-22 Yad yad acarati etc. Na me etc. The Bhagavat cities Himself as an example to illustrate the idea that to favour the world is the [only] purpose for such a person to exert in action, eventhough he has already attained whatever is to be attained, and is fully satisfied in his mind.
