Lord Vishnu is one of the three principal male deities in Hinduism, together with Brahma, the creator, and Shiva, the destroyer. They are collectively known as the TRIMURTI. He has assumed 10 incarnations as a member of the Trinity, and the ten Avatars of Lord Vishnu, also known as the Dashavatara, are the many shapes He took while the cosmos was in upheaval. Vishnu’s Avatars all had the same goal in mind, although they went about achieving it in various ways. This heavenly aim was to restore Dharma, or justice, and to preserve the earth and its inhabitants from evils, demons, or Asuras.
In Hinduism, Matsya (Fish in Sanskrit) was the first Avatar of Vishnu. The great flood is mentioned in Hindu mythology literature like as the Satapatha Brahmana, where the Matsya Avatar appears to save the righteous and the first man, Manu, and advises him to construct a massive boat. Lord Matsya is usually shown as a four-armed figure with a man’s upper torso and a fish’s bottom body.
It is stated that during the Satya Yuga, the inhabitants of the planet became irreligious and unruly in their behaviour. This is when the Gods decided to flood the world in order to prepare it for the restoration process. Lord Vishnu had given Lord Brahma, the creator, the instructions to redesign the planet. The Vedas, Hinduism’s four sacred scriptures, provided these rules. Lord Brahma chose to take a break before embarking on this monumental undertaking since he was exhausted from the process of creation. At this time, a horse-headed demon named Hayagriva emerged from Brahma’s nostril and took the Vedas from him (not to be confused with Lord Hayagriva, the incarnation of Vishnu who is regarded a symbol of learning and knowledge). Then Hayagriva went to hide deep below the earth’s waters. Meanwhile, a devout king named Satyavrata, a great devotee of Lord Vishnu, worshipped Him on a daily basis and desired to see Him. As a result, Lord Vishnu decided to pay Manu a visit.
According to the Matsya Purana, the tale proceeds like this:
Satyavrata, the monarch of pre-historic Dravida and a Vishnu devotee who subsequently became known as Manu, was washing his hands in a river when a little fish swam into his hands and begged him to preserve its life. He put it in a jar, but it quickly outgrew it. He tried moving it to a tank, a river, and eventually the ocean, but it didn’t work. The fish then showed himself to be Vishnu, who warned him that a flood would occur in seven days, destroying all life on the planet. Manu was taught by the fish that towards the conclusion of the Kali Yug, the horse who dwelt at the bottom of the ocean would open her mouth and emit a toxic fire. This fire will consume the entire cosmos, including Gods, stars, and everything else. The seven doomsday clouds would then flood the world, turning it into a single ocean. As a result, the fish told Satyavrata to construct an ark and load it with “all therapeutic plants, all sorts of seeds, and the seven saints,” as well as the snake Vasuki and other creatures. Manu’s ark was nearly finished as the deluge arrived. As the flood surged across the country, Manu inquired of Vishnu as to why mankind had to suffer such a terrible destiny, to which Matsya Vishnu replied that he was the only moral man living and would be the father of future generations of men. Matsya assassinated Hayagriva and handed the Vedas back to Brahma. Then, using Vasuki as a rope, he hooked himself to Manu’s ark and shielded them from the storm and floods. Matsya Vishnu left Manu and the others in the Himalayas when the storms passed and the water receded, so they might resume human civilisation.
