Srimad-Bhagavatam: Canto 3 - Chapter 1 - Verse 30

Sanskrit:

खुरै: क्षुरप्रैर्दरयंस्तदापउत्पारपारं त्रिपरू रसायाम् ।ददर्श गां तत्र सुषुप्सुरग्रेयां जीवधानीं स्वयमभ्यधत्त ॥ ३० ॥

ITRANS:

khuraiḥ kṣuraprair darayaṁs tad āpautpāra-pāraṁ tri-parū rasāyāmdadarśa gāṁ tatra suṣupsur agreyāṁ jīva-dhānīṁ svayam abhyadhatta

Translation:

Lord Boar penetrated the water with His hooves, which were like sharp arrows, and found the limits of the ocean, although it was unlimited. He saw the earth, the resting place for all living beings, lying as it was in the beginning of creation, and He personally lifted it.

Purport:

The word rasāyām is sometimes interpreted to mean Rasātala, the lowest planetary system, but that is not applicable in this connection, according to Viśvanātha Cakravartī Ṭhākura. The earth is seven times superior to the other planetary systems, namely Tala, Atala, Talātala, Vitala, Rasātala, Pātāla, etc. Therefore the earth cannot be situated in the Rasātala planetary system. It is described in the Viṣṇu-dharma: Therefore the Lord found the earth on the bottom of the Garbhodaka Ocean, where the planets rest during the devastation at the end of Brahmā’s day.
