When all the warriors were killed and Duryodhana was struck down, when for the battle the empire of Pandu's son became perfectly safe, when all the (Kuru) camp became empty, when the son of Pandu won great glory, what was the cause for which Krishna had once again to go (to Hastinapura)?
निहतेषु तु योधेषु हते दुर्योधने तदा। पृथिव्यां पाण्डवेयस्य नि:सपत्ने कृते युधि॥ विद्रुते शिबिरे शून्ये प्राप्ते यशसि चोत्तमे। किं न तत् कारणं ब्रह्मन् येन कृष्णो गतः पुनः॥
