न मे पार्थास्ति कर्तव्यं त्रिषु लोकेषु किञ्चन | नानवाप्तमवाप्तव्यं वर्त एव च कर्मणि ||
Na me parthasti kartavyam
O Arjuna, there is nothing in the three worlds that I must do, yet I continue to act.
Modern Application: Act not out of need, but out of purpose.
Deep Wisdom: Krishna sets Himself as an example — even without personal need, He acts for the world.
