Incarntions Of Lord Vishnu

The third incarnation among the Ten Incarnations is Varaha avatara, (Boar incarnation.) At the beginning of the creation of the universe, Brahma, a male named Svayambhuva Manu and a female named Satarupa manifested from his body. By the desire of Brahma, Svayambhuva Manu accepted Satarupa as his wife for the purpose of creation. Seeing the earth submerged in the water of annihilation and desiring to seek a dwelling place for the living beings, Manu approached his father Brahma and prayed to him to rescue the earth. When Brahma saw the earth submerged in the water, he thought for a long time about how it could be rescued. He had earlier established the earth after removing all the water but he could not understand why the earth had sunk into the water again. He had been appointed for the work of creation but the earth had become inundated in a deluge and had sunk down to the Rasatala planetary system.
Even after much effort, Brahma was not able to think of any solution. At last, he took shelter of the Supreme Lord Visnu. While Brahma was still deep in thought, a small boar the size of the tip of a thumb manifested from his nose. But the most surprising thing is that the small boar expanded in front of Brahma and within moments, filled the sky and assumed a form as big as an elephant. Brahma, together with the great brahmanas like Marici, as well as the Four Kumaras and Svayambhuva Manu saw the transcendental Varaha form and began to discuss among them. Lord Brahma thought that this was some denizen of the transcendental world in disguise; traveling in the form of a boar.
In this way, while Brahma was deliberating with his associates, Sri Hari roared tumultuously like the great mountain Giriraja. The omnipotent Sri Hari enlivened Brahma and the other highly elevated brahmanas by again roaring with His uncommon voice. The sound of His roar was so sweet that it destroyed all the miseries of the hearer. Brahma, Svayambhuva Manu, and other sages who reside on Janaloka, Tapaloka and Satyaloka, chanted auspicious mantras from the Vedas as offerings to Varahadeva. Lord Visnu in the form of Varaha accepted the prayers of Brahma and other sages and for the benefit of the demigods, entered into the waters of annihilation. Before entering into the water, Lord Varaha rose into the sky lashing His tail. The Lord raised the hair on His shoulders and scattered the clouds in the sky with His hooves. With raised hairs and white tusks, and with luminous effulgence, the Lord's form was brilliant. This is Sri Hari's unique transcendental pastime. Just the remembrance of it causes shivering in the body. He was omnipotent and omniscient, yet like an animal, He searched for the earth by the sense of smell. His external appearance was fearful; however, He pleased the sages engaged in offering prayers by glancing over them and entered into the water. His dive into the water with his thunderbolt-like body divided the ocean. The ocean prayed to Lord out of fear, "Please protect me, O Supreme Lord!"
The Lord of all sacrifices penetrated the water with His hooves, and in the depths of the Rasatala Ocean, He saw the earth lying there as he carried it in his stomach during the time of devastation. Lord Varaha lifted the earth on His tusks and appeared very splendid. At that time, a very powerful demon named Hiranyaksa challenged Him with a huge mace. An enraged Lord Varaha killed the demon within the water, just as a lion kills an elephant. The body, head and face of the Lord became red with the blood of the demon. The Lord, being thus satisfied with the prayers of the great sages, placed the earth on the water with His hooves.
