Janaloka

During the eight thousand yugas (the equivalent of a day and night for Brahma, the Creator), there was a raging fire, and everything on Earth was reduced to ashes. Man had to forsake the Earth and seek refuge in Janaloka. At the approach of night (of Brahma), Vayu, the Wind God, blew furiously. Huge clouds were formed, there was torrential rain, and it resulted in Pralaya Kalpa (the Great Deluge). The Earth sank into the Patala loka, and remained in that state for a thousand years (during a part of that night of Brahma). Shri Maha Vishnu, wanted to rescue the Earth. He assumed the form of Adi Varaha and proceeded to Pataloka. He fought a fierce duel with Hiranyaksa and killed him. He then slashed the water and brought up the Earth on his tusks.
