Varahadeva is the boar incarnation Sri Krsna. He assumed the form of a boar to lift the drowning planet earth from the Garbhodaka Ocean with His tusks.
The demon Hiryanyaksa had thrown the planet earth into this ocean, but the Lord stabbed the demon with His tusks and saved the earth. After describing the appearance of the white Boar Incarnation that had appeared during the Svayambhuva devastation, Maitreya next described the red Boar Incarnation that had appeared during the Chakshusha devastation. Maitreya related these pastimes to Vidura in the same manner in which he had heard them long ago when Lord Brahma had narrated them to the demigods.
