SB 10.62.33
tam naga-pasair bali-nandano bali
ghnantam sva-sainyam kupito babandha ha
usa bhrsam soka-visada-vihvala
baddham nisamyasru-kalaksy arautsit
Translation:
But even as Aniruddha was striking down the army of Bana, that powerful son of Bali angrily caught Him with the mystic naga-pasa ropes. When Usa heard of Aniruddha’s capture, she was overwhelmed with grief and depression; her eyes filled with tears, and she wept.
Purport:
The acaryas explain that Banasura could not actually capture the powerful grandson of Lord Krsna. However, the Lord’s lila-sakti, or pastime potency, allowed this to happen so that the events described in the next chapter could take place.
Thus end the purports of the humble servants of His Divine Grace A.C. Bhaktivedanta Swami Prabhupada to the Tenth Canto, Sixty-second Chapter, of the Srimad-Bhagavatam, entitled “The Meeting of Usa and Aniruddha.”
