कर्मणैव हि संसिद्धिमास्थिता जनकादयः।
लोकसंग्रहमेवापि संपश्यन्कर्तुमर्हसि।।3.20।।
।।3.20।। जनकादि (ज्ञानी जन) भी कर्म द्वारा ही संसिद्धि को प्राप्त हुये लोक संग्रह (लोक रक्षण) को भी देखते हुये तुम कर्म करने योग्य हो।।
If the counterpoint is posed to the previous verse that desireless unattachment should be performed for the purity of the mind and that when spiritual knowledge arises one may abandon prescribed Vedic activities; because otherwise there will be no chance for liberation to one always engaged in actions as stated in the Mundakaya Upanisad I.II.XII: One will be bound by the very actions they perform. In anticipation of such a counterpoint Lord Krishna confirms the authority of previous examples. By referring to King Janaka and by using in the instrumental case the words karmana eva meaning solely by performing actions as given in Panini I:II:LXV it clearly indicates that it is through actions and not by abandoning actions that King Janaka and others like Asvapati achieved the highest goal of moksa or liberation. So one who is knowledgeable of these things must perform their duties to achieve the goal. If another counterpoint is posed that a person devoted to spiritual knowledge duly purifies their mind and then attaining atma-tattva or soul realisation is free from rebirth and is liberated; so what is the necessity to perform further prescribed Vedic injunctions. Lord Krishna anticipating this point replies that one should consider the welfare of the people in general and perform prescribed actions to protect and inspire them as well as for the maintenance of world order and the preservation of creation. That is why one should still perform prescribed Vedic activities.
