Among Lord Vishnu’s Dashavatara, the Varaha avatar is the boar incarnation wherein he rescues Mother Earth(Bhudevi) from the harmful clutches of a demon king named Hiranyaksha.
In the story, Lord Vishnu, in the form of Varaha, descended into the ocean to rescue Bhudevi (the earth) from demon king Hiranyaksha who stole her and hid her in the cosmic ocean. Lord Varaha defeated Hiranyaksha and lifted the earth out of the ocean with his tusks, restoring it to its proper place. He then celebrated the victory over the demon king with a cosmic dance, the Ananta-Vishnu-Nritya.
This legend is believed to symbolize the victory of good over evil, as well as the importance of the earth and the protection of the environment. The Varaha avatar is also seen as a representation of the power of Lord Vishnu to sustain and protect the universe.
