Shiva bearing the descent of the Ganges River as Parvati and Bhagiratha and the bull Nandi look on, folio from a Hindi manuscript by the saint Narayan, circa 1740.

Told and retold in the Ramayana, the Mahabharata and several Puranas, the story begins with a sage, Kapila, whose intense meditation has been disturbed by the sixty thousand sons of King Sagara. Livid at being disturbed, Kapila sears them with his angry gaze, reduces them to ashes, and dispatches them to the netherworld.

Only the waters of the Ganga, then in heaven, can bring the dead sons their salvation. A descendant of these sons, King Bhagiratha, anxious to restore his ancestors, undertakes rigorous penance and is eventually granted the prize of Ganga's descent from heaven. However, since her turbulent force will also shatter the earth, Bhagiratha persuades Shiva in his abode on Mount Kailash to receive Ganga in the coils of his tangled hair and break her fall.

Ganga descends, is tamed in Shiva's locks, and arrives in the Himalayas. She is then led by the waiting Bhagiratha down into the plains at Haridwar, across the plains first to the confluence with the Yamuna at Prayag and then to Varanasi, and eventually to Ganga Sagar, where she meets the ocean, sinks to the netherworld, and saves the sons of Sagara.
