"I have now told thee of the supreme Lord of all creatures. He is also called the Ruler of all and everything. I shall now, O son of Kunti, speak to thee about the sinful creatures of the earth. Listen to me. Those men, O king, are born in the southern region and are called Andrakas, Guhas, Pulindas, Savaras, Chuchukas, Madrakas. Those that are born in the northern region, I shall also mention. They are Yamas, Kamvojas, Gandharas, Kiratas and Barbaras. All of them, O sire, are sinful, and move on this Earth, characterised by practices similar to those of Chandalas and ravens and vultures. In the Krita age, O sire, they were nowhere on earth. It is from the Treta that they have had their origin and began to multiply, O chief of Bharata's race. When the terrible period came, joining Treta and the Dwapara, the Kshatriyas, approaching one another, engaged themselves in battle.
