In ancient times, the sage Bharadvāja’s quest for a son seemed fruitless, and so his son was called Vitatha, meaning “fruitless” or “in vain.” Yet, through destiny’s design, Bharadvāja, though born a Brahmin, became a Kshatriya, and was remembered as Dvimukhyāyana—the one with two fathers—owing to his unique birth and lineage. When Vitatha was born, King Bharata ascended to heaven, and Vitatha’s own heir upon earth was Bhuvamanyu. Bhuvamanyu had four sons, each as mighty and elemental as the great forces of nature: Bṛhatkṣatra, renowned for his valor; Nara, a paragon of strength; Gāgra, also powerful; and Bhīma, famed for his might. From Nara was born Saṃkṛti, whose sons, Guruvīrya and Trideva, became known as the Saṃkṛtis—respected for their strength. Gāgra’s lineage continued through Śinibaddha, and his descendants, the Gāgryas, were celebrated as twice-born Kshatriyas. Bhīma, ever valiant, was called a devourer, and his wife Vishalā bore him three sons: Trayyaruni, Pushkarini, and a third, a monkey. The first two became illustrious sages, while the monkey was honored as a noble warrior. The Gāgryas, Saṃkṛtis, and Viryas were all twice-born, endowed with the qualities of warriors, and they found their spiritual home in the Angirasa branch, particularly associated with Bṛhatkṣatra. Bṛhatkṣatra’s heir was Suhotra, a king of righteous conduct. Suhotra’s son was Hastin, who founded the famed city of Hastinapura, giving it his name. Hastin had three sons, all supremely righteous: Ajamidha, Dvimidha, and Purumidha. Ajamidha’s sons, the Shabhas, were renowned for their noble lineage and, after great austerities, became righteous kings. By the grace of Bharadvāja, their lineage is recounted in detail: In Kesini, Ajamidha begot Kantha, whose son was Medhatithi. From Medhatithi came the Kanthayana Brahmins. In Dhūmini, Ajamidha fathered King Brihadvasu, whose son was Brihadvishnu, then Brihatkarma, and then Brihadratha. The line continued with Vishvajit, followed by Senajit. Senajit had four sons, celebrated throughout the world: Rucirashva, Kavya, Rama of the firm bow, and Vatsa, also known as King Avantaka. These four were collectively called the Parivatsaras. Rucirashva’s son was Prithushena, famed for his deeds, whose son was Para, from whom Nipa was born. Nipa was said to have a hundred sons, all kings known as the Nipas. Among them, Kirtivardhana stood out as the founder of their lineage. In Kampilya, a king named Samara, later called Cheshta Samara, was born. Samara had three sons—Para, Satvada, and another—each endowed with virtue. Para’s son was Vrisha, whose son Sukriti begot Vibraja, a king of all noble qualities. Vibraja’s heir was Anuha, who became the son-in-law of Shuka and the father of the illustrious Rishi. Anuha’s son was Brahmadatta, famed for his austerity; his son was Yogasunu, and then came Vishvaksena, who became king. The radiant sons of this line became kings, though some through wrongful deeds. Vishvaksena’s son was Udaksena, whose heir was Bhallāta—a king who, in earlier times, had slain another king. Bhallāta’s son was Janamejaya, and because of Janamejaya, the mighty Ugrāyudha destroyed all the kings. Curiosity arose: who was Ugrāyudha’s father, and in which lineage was he renowned? For what cause did he destroy all those kings? The answers unfold in the line of Dvimidha. Dvimidha’s son was the learned Yavīnara, whose son was steadfast Satyadhṛti. Satyadhṛti’s son was the mighty Dṛḍhanemi, followed by King Suvarmā. Suvarmā’s son was Sārvabhauma, powerful and renowned as the sole sovereign of the earth. From this great lineage was born the illustrious son of Paurava. Mahatpaurava’s son was Rukmaratha, followed by King Supārśva, and then the righteous Sumati. Sumati’s son was the virtuous and humble Sanati, whose son was Kṛta. Kṛta became a disciple of the great Kauthuma Hiraṇyanābha, who taught him the Sāma Saṃhitās in twenty-four branches—these became known as the Eastern recensions, cherished by the singers of Sāman. From this noble line came Kārti Ugrāyudha, the heroic descendant of Paurava, who slew the ancestor of Pṛṣata and killed the mighty-armed Nīla, lord of the Pañcālas. Ugrāyudha’s heir was the illustrious Kṣema, followed by the hero Suvīra, then Nṛpañjaya, and Vīraratha—these kings are remembered as the Pauravas. From Ajamidha and Nīlinī was born King Nīla, whose intense austerities brought forth Suśānti. Suśānti’s son was Purujānu, whose son was Rikṣa. From Rikṣa came several branches: Mudgala, Sṛñjaya, King Bṛhadiṣu, the valiant younger Yavīyān, and Kampilya as the fifth. Thus, the noble lineages flourished, each branch giving rise to kings, sages, and warriors, whose deeds and virtues became woven into the great tapestry of dharma and history.
