From Brahma the knowledge progressively passed to Pulastyaa, Parashurama, Ugra and Manu. Vedavyasa, the composer of the Puranas, will expound it in the future and the knowledge will spread through Lomaharshana and Shounaka. (Remember that the Varaha was telling the stories much before Vedavyasa.) He who reads and worships this text on avadashi in the month of Kartika, attains all his desires on heaven and on earth.

(You will have noticed that this alludes to the existence of a text of the Varaha Purana prior to Vedavyasa’s composition.)

The story of the Earth’s Rescue
The sage Sanatkumara once asked the earth to recount the story of her rescue at the hands of the boar incarnation.

When the earth sank to the underworld, she appealed to Vishnu to save her. The hymn that she used is known as keshava stuti. It delivers one from sin, poverty and childlessness, and leads to the attainment of Vishnuloka (the abode of Vishnu).

One hearing the earth’s appeal, Vishnu reassured her and manifested himself in the form of a gigantic boar. The boar was six thousand yojanas (an unit of measurement) tall and three thousand yojanas wide. The boar entered the ocean to rescue the earth. Such was the shock of the boar’s entry that there were tremors on earth and several mountains were dislodged and also fell into the sea.

The boar discovered the earth in the underworld and raised her up on his tusks. That was indeed a grand and awe-inspiring sight. For a thousand years the boar held up the earth on his tusks. When creation started again, the earth was placed in her appointed place.
