Srimad-Bhagavatam: Canto 8 - Chapter 1 - Verse 13
Sanskrit:
उपर्यधश्चात्मनि गोत्रनेत्रयो:परेण ते प्राविशता समेधिता: ।ममन्थुरब्धिं तरसा मदोत्कटामहाद्रिणा क्षोभितनक्रचक्रम् ॥ १३ ॥
ITRANS:
upary adhaś cātmani gotra-netrayoḥpareṇa te prāviśatā samedhitāḥmamanthur abdhiṁ tarasā madotkaṭāmahādriṇā kṣobhita-nakra-cakram
Translation:
The demigods and demons worked almost madly for the nectar, encouraged by the Lord, who was above and below the mountain and who had entered the demigods, the demons, Vāsuki and the mountain itself. Because of the strength of the demigods and demons, the Ocean of Milk was so powerfully agitated that all the alligators in the water were very much perturbed. Nonetheless the churning of the ocean continued in this way.
