In the Vishnu Purana, the churning of the ocean of Milk takes place after the sage Durvasas - stated by Wilson to be 'an incarnation of a portion of Siva' (footnote 1, pp. 135) - curses Indra, resulting in the ruin of the Devas, the Earth, and the general population, as 'all beings became devoid of steadiness' and morality. On the northern shore of the Ocean of Milk, Hari is sought for refuge, and enjoins the Devas to churn the Ocean for Ambrosia with the Asuras, using the Mandara Mountain as a churning rod and Vasuki as the rope.
