The Varaha Avatar of Lord Vishnu holds great significance in Hindu mythology. This incarnation took place when the Earth was in crisis, hidden in the netherworld (Patala) by the demon Hiranyaksha. The story is as follows:

Once upon a time, a fearsome demon named Hiranyaksha received a boon from Lord Brahma that no deity, human, or animal could kill him. Empowered by this boon, he became extremely powerful and arrogant. In his arrogance, he submerged the Earth (Bhudevi) in the ocean and hid it in the netherworld.

Distressed by this crisis on Earth, the gods sought refuge with Lord Vishnu. They prayed to him to save them from this crisis and restore the Earth.

Hearing their prayers, Lord Vishnu took the form of Varaha (a boar). This form was of a gigantic, powerful, and fierce boar that resonated throughout the universe.

In his Varaha Avatar, Lord Vishnu set out for the netherworld. Upon reaching there, he saw that Hiranyaksha had the Earth under his control. Lord Varaha challenged Hiranyaksha to battle. A fierce battle ensued, causing the earth and sky to tremble. Ultimately, Lord Varaha killed Hiranyaksha with his sharp tusks.

After vanquishing Hiranyaksha, Lord Varaha lifted the Earth on his tusks and restored it above the ocean. He placed the Earth back in its position, stabilizing it. Thus, in his Varaha Avatar, Lord Vishnu saved the Earth and restored it.

This story of Lord Vishnu's Varaha Avatar teaches us that whenever unrighteousness prevails and righteousness is in crisis, Lord Vishnu incarnates in some form to establish righteousness and destroy unrighteousness. In the Varaha Avatar, Lord Vishnu demonstrated that whenever the Earth is in crisis, he will certainly appear to protect it.
