Avatar 3 :
Varaha is half-man, half-boar, and is engaged in picking up the earth. He has 2 or 4 arms holding the attributes of Vishnu. Vishnu came down to earth in the form of this avatar to kill Hiranyaksha, an asura (demon) who had become invincible. In asking Brahma to grant him invincibility Hiranyaksha cited all the living things on earth and in
the universe but forgot to mention the boar and Vishnu took this opportunity to defeat him in this form. Varaha dove also to the bottom of the ocean to save the earth after Hiranyaksa put it there.
