Mahabharata Adi Parva Chapter 75

Mahabharata Adi Parva Chapter 75 "Vaisampayana said, 'Hear now, as I recite the recorded genealogy, that is sacred and subservient to religion, profit and pleasure, of these royal sages—Daksha, the lord of creation, Manu, the son of Surya, Bharata, Ruru, Puru, and Ajamidha. I shall also recite to thee, O sinless one, the genealogies of the Yadavas and of the Kurus and of the king of the Bharata line. These genealogies are sacred and their recitation is a great act of propitiation. That recitation conferreth wealth, fame and long life. And, O sinless one, all these I have named shone in their splendour and were equal unto the great Rishis in energy. "Prachetas had ten sons who were all devoted to asceticism and possessed of every virtue. They burnt, of old, by the fire emanating from their mouths, several plants of poisonous and innumerable large trees that had covered the Earth and became a source of great discomfort to man. After these ten, was born another named Daksha. It is from Daksha that all creatures have sprung. Therefore is he, O tiger among men, called the Grandfather. Born of Prachetas the Muni Daksha, uniting himself with Virini, begat a thousand sons of rigid vows, all like himself. And Narada taught these thousand sons of Daksha the excellent philosophy of Sankhya as a means of salvation. And, O Janamejaya, the lord of creation, Daksha, then, from the desire of making creatures, begat fifty daughters. And he made all of them his appointed daughters (so that their sons might be his sons also for the performance of all religious acts). And he bestowed ten of his daughters on Dharma, and thirteen on Kasyapa. And he gave twenty-seven to Chandra, who are all engaged in indicating time. And Kasyapa, the son of Marichi, begat on the eldest of his thirteen wives, the Adityas, the celestials endued with great energy and having Indra as their head and also Vivaswat (the Sun). And of Vivaswat was born the lord Yama. And Martanda (Vivaswat) also begat another son after Yama, gifted with great intelligence and named Manu. And Manu was endued with great wisdom and devoted to virtue. And he became the progenitor of a line. And in Manu's race have been born all human beings, who have, therefore, been called Manavas. And it is of Manu that all men including Brahmanas, Kshatriyas, and others have been descended, and are, therefore, all called Manavas. Subsequently, O monarch, the Brahmanas became united with the Kshatriyas. And those sons of Manu that were Brahmanas devoted themselves to the study of the Vedas. And Manu begat ten other children named Vena, Dhrishnu, Narishyan, Nabhaga, Ikshvaku, Karusha, Saryati, the eighth, a daughter named Ila, Prishadhru the ninth, and Nabhagarishta, the tenth. They all betook themselves to the practices of Kshatriyas. Besides these, Manu had fifty other sons on Earth. But we heard that they all perished, quarrelling with one another. The learned Pururavas was born of Ila. It hath been heard by us that Ila was both his mother and father.
