The Churning of the Sea of Milk.
The 'Churning of the Sea of Milk', a mythological scene from Vishnu lore. The gods (devas) and demons (asuras) use the serpent Vasuki as a cord wound around holy Mount Mandara, which rises from the Sea of Milk. By pulling alternately on the serpent, together they churn the primordial ocean in order to produce 'amrita', the elixir of immortality.
