khuraiḥ kṣuraprair darayaṁs tad āpa
utpāra-pāraṁ tri-parū rasāyām
dadarśa gāṁ tatra suṣupsur agre
yāṁ jīva-dhānīṁ svayam abhyadhatta
khuraiḥ—by the hooves; kṣurapraiḥ—compared to a sharp weapon; darayan—penetrating; tat—that; āpaḥ—water; utpāra-pāram—found the limitation of the unlimited; tri-paruḥ—the master of all sacrifices; rasāyām—within the water; dadarśa—found; gām—the earth; tatra—there; suṣupsuḥ—lying; agre—in the beginning; yām—whom; jīva-dhānīm—the resting place for all living entities; svayam—personally; abhyadhatta—uplifted.
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.
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.
