Six sons, begotten (by Aryans) on women of equal and the next lower castes (Anantara), have the duties of twice-born men; but all those born in consequence of a violation (of the law) are, as regards their duties, equal to Sudras.
तपोबीजप्रभावैस्तु ते गच्छन्ति युगे युगे । उत्कर्षं चापकर्षं च मनुष्येष्विह जन्मतः ॥ ४२ ॥
By the power of austerities and of the seed (from which they sprang), these (races) obtain here among men more exalted or lower rank in successive births.
But in consequence of the omission of the sacred rites, and of their not consulting Brahmanas, the following tribes of Kshatriyas have gradually sunk in this world to the condition of Sudras;
(Viz.) the Paundrakas, the Kodas, the Dravidas, the Kambogas, the Yavanas, the Sakas, the Paradas, the Pahlavas, the Kinas, the Kiratas, and the Daradas.
मुखबाहूरुपद्जानां या लोके जातयो बहिः । म्लेच्छवाचश्चार्यवाचः सर्वे ते दस्यवः स्मृताः ॥ ४५ ॥
All those tribes in this world, which are excluded from (the community of) those born from the mouth, the arms, the thighs, and the feet (of Brahman), are called Dasyus, whether they speak the language of the Mlekkhas (barbarians) or that of the Aryans.
