The myth of origin of Kanchis

• Mahabharata, Book 1, Chapter 177

When the sage Vasistha was attacked by king Viswamitra's army, Vasistha's cow, Kamadehnu, brought forth from her tail, an army of Palhavas, and from her udders, an army of Dravidas and Sakas; and from her womb, an army of Yavanas, and from her dung, an army of Savaras; and from her urine, an army of Kanchis; and from her sides, an army of Savaras. And from the froth of her mouth came out hosts of Paundras and Kiratas, Yavanas and Sinhalas, and the barbarous tribes of Khasas and Chivukas and Pulindas and Chinas and Hunas with Keralas, and numerous other Mlechchhas.

In the ancient Indian literature, cow is a symbol of earth or land. Thus the myth mentioned above simply means that, these tribes gathered for the protection of sage Vasistha's land against the army of king Viswamitra.
