Manu gathered together all the different seeds and “set sail in an excellent vessel on the surging sea”. He thought of the fish, and it arose out of the waters like an island; he cast a noose which he fastened to the horns on its head, and the fish towed the ark over the roaring sea; tossed by the billows the vessel reeled about like one who is drunk. No land was in sight. “There was water everywhere, and the waters covered the heaven and the firmament also.... When the world was thus flooded none but Manu, the seven Rishis, and the fish could be seen.”

After many long years the vessel was towed to the highest peak of the Himavat, which is still called Nau-bandhana (the harbour), and it was made fast there. The fish then spoke and said: “I am Brahma, the Lord of all Creatures; there is none greater than me. I have saved thee from this cataclysm. Manu will create again all beings—gods, Asuras, and men, and all those divisions of creation which have the power of locomotion and which have it not. By practising severe austerities he will acquire this power....”

Then Manu set about creating all beings in proper and exact order.[178]

Markandeya elsewhere described the universal cataclysm with more detail. After a drought lasting for many years, seven blazing suns will appear in the firmament; they will drink up all the waters. Then wind-driven fire will sweep over the earth, consuming all things; penetrating to the nether world it will destroy what is there in a moment; it will burn up the Universe. Afterwards many-coloured and brilliant clouds will collect in the sky, looking like herds of elephants decked with wreaths of lightning. Suddenly they will burst asunder, and rain will fall incessantly for twelve years until the whole world with its mountains and forests is covered with water. The clouds will vanish. Then the Self-created Lord, the First Cause of everything, will absorb the winds and go to sleep. The Universe will become one dread expanse of water.

Account has to be taken of the persistent legend regarding the ambrosia which gave strength to the gods and prolonged their existence. In “Teutonic mythology” it is snatched by Odin from the giants of the Underworld, and is concealed in the moon, which is ever pursued by the demon wolf Managarm, who seeks to devour it.

The development of the Indian form of the myth is found in the story of “The Churning of the Ocean”, which is dealt with in the Mahábhárata, the Ramáyana, and several of the Puranas.

According to the epics, the ambrosia, the Indian name of which is amrita (both words implying immortality), was required by the gods so as to enable them to overcome the demons. In Vishnu Parva, however, a Brahmanic addition to the myth was made so as to exalt a sage and illustrate the power he could exercise over the old Vedic deities. It is related that Durvásas obtained from a merry nymph a sweet-scented, inspiring garland which made him dance. He presented it to Indra, who placed it on the head of his elephant. The elephant then began to prance about, and grew so excited that it cast the garland on the ground. Durvásas was enraged because that his gift was slighted in this manner, and cursed Indra and foretold the ruin of his kingdom. Thereafter the king of the gods began to suffer loss of power, whereat the other deities became alarmed, fearing that the demons would overcome him in battle. Appeal was made to Brahma, who referred the gods to Vishnu, the Preserver. That supreme being commanded that the ocean should be churned for amrita.

In the epics the gods allied themselves with the demons to procure amrita from Vishnu's Sea of Milk. The “churning stick” was the mountain Mandara, and the “churning rope” the serpent Vasuka[179] (Ananta or Shesha). Vishnu said: “The demons must share in the work of churning, but I will prevent them from tasting of the amrita, which must be kept for Indra and the gods only.”

The gods carried the mountain Mandara to the ocean, and placed it on the back of Kurma, the king of tortoises, who was an incarnation of Vishnu.[180] Round the mountain they twisted the serpent, which was “a part of a part of Vishnu”, the Asuras holding its hood and the gods its tail. As a result of the friction caused by the churning, masses of vapour issued from the serpent's mouth which, becoming clouds charged with lightning, poured down refreshing rains on the weary workers. Fire darted forth and enwrapped the mountain, burning its trees and destroying many birds, and the lions and elephants that crouched on its slopes. In time the Sea of Milk produced butter flavoured by the gums and juices which dropped from the mountain. The gods grew weary, but Vishnu gave them fresh strength to proceed with the work. At length the moon emerged from the ocean; then arose the Apsaras, who became nymphs in Indra's heaven; they were followed by the goddess Lakshmi, Vishnu's white steed, and the gleaming gem which the god wears on his breast. Then came Dhanwantari, the physician of the gods, who carried a golden cup brimming with amrita. Beholding him, the Asuras cried out: “The gods have taken all else; the physician must be ours.”

Next arose the great elephant Airávata, which Indra took for himself. The churning still went on until the blue, devastating poison appeared and began to flow over the earth, blazing like a flame mixed with fumes. To save the world from destruction, Shiva swallowed the poison and held it in his throat. From that time he was called Nilakantha, “the blue-throated”.
