Final answer:
The relief sculpture of Churning of the Ocean of Milk at Angkor Wat depicts the Hindu mythological event of Samudra Manthan, where gods and demons churn the ocean to obtain Amrita, the nectar of immortality.
Step-by-step explanation:
The relief sculpture of Churning of the Ocean of Milk at Angkor Wat, Cambodia, is a profound representation of a Hindu mythological event. This event is known as the Samudra Manthan, a pivotal moment in Hinduism where deities (devas) and demons (asuras) worked together to churn the ocean using the serpent Vasuki and Mount Mandara to obtain the nectar of immortality (Amrita).
This intricate relief sculpture captures the dynamic motion of this cosmic tug-of-war and is a key highlight of the bas-reliefs found in the galleries of Angkor Wat. The symbolism and detailed work of the sculpture reflect the great importance placed on this myth within the Hindu religion and the cultural significance it had during the time of its creation.
