Sagara Obtains a Boon from ShivaKing Sagara, powerful but sonless, retreats to Mount Kailasa with his two wives and performs austerities so severe that Shiva himself appears before them. The god grants a boon — but the terms are strange, and the cost is hidden in plain sight.
Sagara's Sacrificial Horse DisappearsKing Sagara begins a horse sacrifice, sending his sons to guard the roaming horse across the earth. When the horse vanishes at the edge of a waterless ocean, his sons return empty-handed. Sagara, furious, commands them to search again — and not to return without the horse.
Sagara Banishes His Son AsamanjaNarada brings Sagara the news that his sixty thousand sons have been burned to ashes by Kapila's energy. Sagara steadies himself, recalling the words of Sthanu, and summons his grandson Anshuman — but before telling him about the dead, he reveals something else: he had already banished Anshuman's father, his own son Asamanja, for the welfare of the citizens. Yudhishthira asks why, and Lomasha recounts how Asamanja used to seize the infants of the city and throw them into the river.
Sagara's Lineage Continues Through Anshuman and DilipaAfter completing the sacrifice, Sagara is honored by the gods and hands the kingdom to his grandson Anshuman before departing to heaven. Anshuman rules well, then passes the throne to his son Dilipa — who, grieving for his dead ancestors, tries desperately to bring down the Ganga but fails, and eventually hands the burden to his son Bhagiratha before retiring to the forest.
Anshuman Retrieves the Sacrificial Horse from KapilaSagara, tormented by the loss of his sixty thousand sons and the stalled sacrifice, commands his grandson Anshuman to retrieve the horse from hell. Anshuman descends through the torn earth, finds the sage Kapila and the horse, and bows before the ancient rishi — asking not just for the horse, but for water to purify his dead fathers.
Bhagiratha's Austerities and Ganga's AppearanceFor a thousand celestial years, King Bhagiratha lives on nothing but fruits, roots, and water, performing terrible austerities to bring the river Ganga down from heaven. When she finally appears in personified form and asks what he desires, he tells her the story of his grandfathers — the sixty thousand sons of Sagara, destroyed by the sage Kapila, whose ashes cannot reach heaven without being touched by her waters. Ganga agrees to descend, but warns him that no one in the three worlds can withstand her force except Nilakantha Maheshvara himself.
