O Mahārāja Parīkṣit, subduer of all enemies, after Lord Brahmā finished speaking to the demigods, he took them with him to the abode of the Supreme Personality of Godhead, which is beyond this material world. The Lord’s abode is on an island called Śvetadvīpa, which is situated in the Ocean of Milk.
