In battles that followed this incident, Devas were defeated and Asuras (demons) led by king Bali, gained control of the universe. Devas sought help from Lord Vishnu who advised them to treat asuras in a diplomatic manner. Devas formed an alliance with asuras to jointly churn the ocean for the nectar of immortality and to share it among them. However, Lord Vishu told Devas that he would arrange that they alone obtain the nectar.

Churning the Milky Ocean
The churning of the Ocean of Milk was an elaborate process. Mount Mandaranchal was used as the dasher (churning tool), and Vasuki, the king of serpents, became the churning rope. The gods held the tail of the snake, while the demons (Asuras) held its head, and they pulled on it alternately causing the mountain to rotate, which in turn churned the ocean. However, once the mountain was placed on the ocean, it began to sink. Vishnu in his second incarnation, in the form of a turtle Kurma, came to their rescue and supported the mountain on his back.
