Legend has it that Demon Hiranyaksha had pushed the Mother Earth down into oceans and Lord Vishnu appeared as Varaha, the boar incarnation, to rescue it. Hiranyaksha is the brother of Hiranyakashipu who was annihilated by Lord Vishnu as Narasimha – half-man half-lion.
Hiranyaksha means the golden-eyed and he was the son of Sage Kashyapa and Diti.

In the previous birth Hiranyaksha and Hiranyakashipu were the brothers Jaya and Vijaya – they were the gate keepers of the Vaikunta or Heaven. They became demons due to a curse and they were saved from the curse by Lord Vishnu by removing their demonic traits.
Hiranyaksha pushing the earth into the ocean symbolically suggests land grabbing and greed.
The stories in the Puranas state that Hiranyaksha started troubling saints, humans and Devas. Finally, he decided to drag and throw the earth into the ocean. When he did it Mother Earth gave a huge cry and Vishnu appeared in the form of Varaha and fought and killed Hiranyaksha and restored Mother Earth.
