In ancient times, King Sagara, accompanied by all his sons, undertook a great endeavor: they dug up the land, searching relentlessly until their efforts led them to the very edge of the vast ocean. There, at the boundary between earth and sea, they beheld the primordial Lord—Hari, who is Kṛṣṇa, Prajāpati, Viṣṇu in the form of Kapila, Haṃsa, and Nārāyaṇa, the Supreme Lord himself. As the sons of Sagara approached the divine radiance of the Lord, they were overwhelmed by his brilliance. Unable to withstand it, all but four of the king’s sons were consumed by that fiery splendor. The four who survived were Barhiketu, Saketu, and the two devoted to dharma, Śūra and Pañcavana. These noble ones became the progenitors of Sagara’s lineage. Blessed by the Lord Hari, Nārāyaṇa, Sagara received divine boons: the promise of an undiminished lineage, the right to perform a hundred Aśvamedha horse sacrifices, the birth of a mighty son, sovereignty over the ocean, and eternal residence in heaven. The ocean itself, having taken the sacrificial horse, paid homage to Sagara, the lord of rivers, and thus came to be known as ‘Sāgara.’ Retrieving the horse from the ocean, Sagara performed the Aśvamedha sacrifice a hundred times. Yet, the sixty thousand sons who had followed the horse were burned away, their radiance merging into Nārāyaṇa. Thus, it is said, sixty thousand sons perished. Hearing this, the sages asked, “How were the mighty sons of King Sagara born? By what means did he come to have sixty thousand valiant sons?” The Sūta replied: Sagara had two wives, both purified by austerity. The elder was Keśinī, daughter of the king of Vidarbha, and the younger, the supremely virtuous daughter of Ariṣṭanemi, unmatched in beauty on earth. Desiring offspring, both wives worshipped the sage Urva with great austerity. Pleased, the sage granted them a boon: one wife would bear a single son, destined to continue the lineage, and the other would give birth to sixty thousand sons. Keśinī chose to bear the one son who would be the pride of the lineage, while Sumati, the sister of Suparṇa, accepted the destiny of nurturing sixty thousand sons. King Sagara undertook to care for them all. In time, Keśinī gave birth to her son, Asamañja, the eldest among Sagara’s children and scion of the Kakutstha line. Sumati, the illustrious queen, gave birth to a single womb shaped like a jar, from which sixty thousand sons emerged. She placed these embryos in jars filled with ghee, and the king appointed a nurse for each to ensure their growth. After nine months, the noble sons emerged, bringing great joy to Sagara. When they came of age, these sixty thousand sons, followers of the sacrificial horse, entered the forest. Among them, Asamañja, the eldest and a tiger among men, bore the sacrificial crest. Yet, despite his noble birth, Asamañja was expelled by his father for his conduct. His son, Aṃśumān, was valorous and righteous. Aṃśumān’s son was the renowned Dilīpa, and from Dilīpa was born the mighty and heroic Bhagīratha. It was Bhagīratha who, through great sacrifice, brought the sacred river Gaṅgā—adorned with celestial vehicles—down from the heavens. Because of his deeds, Gaṅgā is also called Bhāgīrathī by those who know the lineage. Bhagīratha’s son was named Śruta, whose own son was Nābhāga, ever devoted to righteousness. Nābhāga’s son was Ambarīṣa, and from him came Sindhudvīpa. By the strength of Nābhāga and Ambarīṣa, the earth was well protected and freed from all suffering. Sindhudvīpa’s son was the valorous Ayutāyu, and his heir was Ṛtuparṇa, famed for his wisdom. Ṛtuparṇa was a friend of King Nala, renowned for his knowledge of dice and the human heart; both Nalas are celebrated in ancient lore—one, son of Vīrasena, the other, foremost of the Ikṣvāku line. Ṛtuparṇa’s son, fulfilling all desires, became lord of the people. His son was Sudāsa, a king whose face was likened to a swan; Sudāsa’s son was Saudāsa, also known as Kalmāṣapāda and Mitrasaha. The great sage Vasiṣṭha, of immense brilliance, begot Aśmaka upon Kalmāṣapāda’s field to continue the Ikṣvāku line. Aśmaka’s son was Urakāma, whose son was Mūlaka. Of Mūlaka, it is told that, fearing Rāma, he lived surrounded by women and wore women’s armor for protection. Mūlaka’s son was the righteous King Śataratha, from whom came the powerful King Vaiḍiviḍa. Vaiḍiviḍa, glorious and accomplished, was father to Viśvamahat, son of Putrīka. Dilīpa, also known as Khaṭvāṅga, was his son—a king who, coming from heaven to earth, lived but a moment, yet through wisdom and truth united the three worlds. Khaṭvāṅga’s son was Dīrghabāhu, from whom was born Raghū. Raghū’s son was Aja, and Aja’s son was the mighty Daśaratha, the delight of the Ikṣvāku lineage. Daśaratha’s son was Rāma, famed throughout the world for his heroism and righteousness. His brothers were Bharata, Lakṣmaṇa, and the mighty Śatrughna. Śatrughna, having slain Mādhava and Lavaṇa, journeyed to Madhuvana, where he established the city of Mathurā. Thus unfolds the sacred lineage of King Sagara, the deeds of his descendants, and the blessings of the Lord that shaped the destiny of kings and the world.
