TRANSLATION
Lord Boar penetrated the water with His hoofs, which were like sharpened arrows, and He found out 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 Thākura. 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 :
pātāla-mūleśvara-bhoga-saṁhatau 
  vinyasya pādau pṛthivīṁ ca bibhrataḥ 
  yasyopamānaṁ na babhūva so cyuto 
  mamāstu māṅgalya-vivṛddhaye hariḥ
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.
