Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 42

Sanskrit:

तद् ब्रूहि मे महायोगिन्परं कौतूहलं गुरो ।नूनमेतद्धरेरेव माया भवति नान्यथा ॥ ४२ ॥

ITRANS:

tad brūhi me mahā-yoginparaṁ kautūhalaṁ guronūnam etad dharer evamāyā bhavati nānyathā

Translation:

O greatest yogī, my spiritual master, kindly describe why this happened. I am very much curious to know about it. I think that it was nothing but another illusion due to Kṛṣṇa.

Purport:

Kṛṣṇa has many potencies: parāsya śaktir vividhaiva śrūyate (Śvetāśvatara Upaniṣad 6.8). The description of Aghāsura was disclosed after one year. Some act of Kṛṣṇa’s potency must have been involved. Therefore Mahārāja Parīkṣit was very curious to know about this, and he requested Śukadeva Gosvāmī to explain it.
