Hear now the wondrous lineage of the ancient clans, as recounted in the sacred tradition. Among the foremost sons of Danu were mighty beings: Dvimūrdhā, Śakuni, Śaṅkuśirodhara, Ayomukha, Śambara, and one known as Kapiśa. With them stood Mārīci, Meghavān, Irā, Garbhaśiras, Vidrāvana, Ketu, Ketuvīrya, and Śatahrada—each powerful and renowned. Indrajit, Saptajit, Vajranābha, Ekacakra, Mahābāhu, Vajrākṣa, and Tāraka were also counted among these illustrious asuras. Asilomā, Pulomā, the great asura Bindurbāṇa, Svarbhānu, and Vṛṣaparvan were likewise prominent sons of Danu. Svarbhānu’s daughter was Prabhā, radiant in her own right, and Śacī, the daughter of Puloman, became celebrated among the divine. Upadānavī, Mandodarī, and Kuhū all became wives of Maya, the great architect. Vṛṣaparvan’s daughters were Śarmiṣṭhā, Sundarī, and Candra, while Pulomā and Kālakā, daughters of Vaiśvānara, also contributed to this rich lineage. From these unions, especially through Mārīca, there arose a mighty host—sixty thousand Dānavas, strong and numerous. Mārīca was the progenitor of the Paulomas and Kālakeyas, who, blessed with invulnerability to the gods, took residence in Hiraṇyapura. Granted boons by the four-faced Brahmā himself, they were eventually slain in battle. Vipracitti, another mighty asura, fathered the Saiṃhikeyas on Siṃhikā. The line continued with the thirteen nephews of Hiraṇyakaśipu: Vyaṃsa, Kalpa, Nala, and Vātāpi, followed by Ilvala, Namuci, Śvasṛpa, Ajana, Naraka, Kālanābha, and Saramāṇa. The Kālavīyas, famed for enhancing the Danu lineage, also arose, and from Saṃhrāda the Daitya came the Nivātakavacas, invulnerable to gods, Gandharvas, serpents, and Rākṣasas alike. Yet, these too met their end, slain by Arjuna in battle, after seeking refuge with Bharga. From the union of Mārīca and Tāmrā were born six daughters: Śukī, Śyenī, Bhāsī, Sugrīvī, Gṛdhrikā, and Śuci. Śukī, following the path of righteousness, became the mother of parrots and owls; Śyenī bore hawks; Bhāsī gave birth to kites, and Kurarī produced her own kind. Gṛdhrī brought forth vultures and pigeons, while Pārāvatī gave rise to doves and other birds. Haṃsī became the mother of swans, cranes, and krauñcas, and Plavā gave birth to waterfowl. Sugrīvī produced goats, horses, sheep, camels, and asses, thus completing the lineage of Tāmrā. Now, hear of Vinatā. From her were born Garuḍa, the mighty lord of birds, and Aruṇa, foremost among the winged. Saudāmanī, a daughter renowned in the heavens, was also born to Vinatā. Aruṇa’s sons were Sampāti and Jaṭāyu; Sampāti’s son was Babhrū, and Śīghraga, famed among all, was also born. From Jaṭāyu came Karṇikāra, the illustrious Śatagāmī, Sārasa, Rajjuvāla, and Bheruṇḍa. Their descendants multiplied among the birds, becoming countless, with sons and grandsons in great number. Surasā, in ancient times, gave birth to a thousand serpents. Kadrū, virtuous one, bore a thousand serpents, each with a thousand heads. Among these, twenty-six became renowned as leaders: Śeṣa, Vāsuki, Karkoṭa, Śaṅkha, Airāvata, Kambala, Dhanaṃjaya, Mahānīla, Padma, Aśvatara, and Takṣaka; also Elāpatra, Mahāpadma, Dhṛtarāṣṭra, Balāhaka, Śaṅkhapāla, Mahāśaṅkha, Puṣpadaṃṣṭra, and Śubhānana; as well as Śaṅkuromā, Bahula, Vāmana, Pāṇina, Kapila, Durmukha, and Patañjali. Their descendants, sons and grandsons, became innumerable; yet, in ages past, most perished in the great snake sacrifice performed by Janamejaya. Kadrū also gave birth to a host of demons, each fierce and wrathful, and Bhīmasena destroyed many of these fanged ones. In a similar way, Surabhi, steadfast in her vows, gave birth to the hosts of Rudras, as well as cows and buffaloes, from her union with Kaśyapa. The sage Kaśyapa also begot the hosts of sages and the Apsarases. Ariṣṭā gave birth to many Kinnaras and Gandharvas. Irā brought forth all grasses, trees, creepers, and shrubs; Viśvā produced Yakṣas and Rākṣasas by the millions. Diti, knowing righteousness, gave birth to forty-nine Maruts from Kaśyapa, all beloved of the immortals. But how did these sons of Diti, the Maruts, become beloved of the gods, though born as rivals? And how did they come to form the highest friendship with the gods? Long ago, in the great battle between the gods and the demons, when Hari had taken away the gods along with their sons and grandsons, the immortals were consumed by grief and retreated to the highest earthly realm. In the sacred field of Syamantapanchaka, on the auspicious bank of the Sarasvati, Diti, devoted to her husband, undertook severe austerities. She, steadfast in her vows and taking the form of a sage, sustained herself on fruits and performed rigorous penances such as the Chandrayana, for more than a hundred years. Though troubled by age and sorrow, she endured, scorched by her own austerity, until she approached Vasiṣṭha and other sages with a question. “O revered ones,” she asked, “tell me of a vow that destroys grief for sons and brings the fruit of good fortune in this world and the next.” Vasiṣṭha and the others replied, “The Madana-Dvādaśī vow—by its power one becomes free from sorrow for sons.” Thus, the sages and listeners asked to hear more of the Madana-Dvādaśī vow, by which Diti regained her forty-nine sons. Now, the tale continues: what was once told by Vasiṣṭha and the others to Diti, the excellent vow, is to be recounted in detail.
