Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 33

Sanskrit:

तं नागपाशैर्बलिनन्दनो बलीघ्नन्तं स्वसैन्यं कुपितो बबन्ध ह ।ऊषा भृशं शोकविषादविह्वलाबद्धं निशम्याश्रुकलाक्ष्यरौत्सीत् ॥ ३३ ॥

ITRANS:

taṁ nāga-pāśair bali-nandano balīghnantaṁ sva-sainyaṁ kupito babandha haūṣā bhṛśaṁ śoka-viṣāda-vihvalābaddhaṁ niśamyāśru-kalākṣy arautsīt

Translation:

But even as Aniruddha was striking down the army of Bāṇa, that powerful son of Bali angrily caught Him with the mystic nāga-pāśa ropes. When Ūṣā heard of Aniruddha’s capture, she was overwhelmed with grief and depression; her eyes filled with tears, and she wept.

Purport:

The ācāryas explain that Bāṇāsura could not actually capture the powerful grandson of Lord Kṛṣṇa. However, the Lord’s līla-śakti, or pastime potency, allowed this to happen so that the events described in the next chapter could take place.
