Mahabharata Karna parva Chapter 44:3

Mahabharata Karna parva Chapter 44:3 The Vahikas drink the milk of sheep and camels and asses and eat curds and other preparations from those different kinds of milk. Those degraded people number many bastards among them. There is no food and no milk that they do not take. The Aratta-Vahikas that are steeped in ignorance, should be avoided.' Thou shouldst know this, O Shalya. I must, however, again speak to thee about what another Brahmana had said unto me in the Kuru court, 'How can one go to heaven, having drunk milk in the town called Yugandhara, and resided in the place called Acyutasthala, and bathed in the spot called Bhutilaya? There where the five rivers flow just after issuing from the mountains, there among the Aratta-Vahikas, no respectable person should dwell even for two days. There are two Pishacas named Vahi and Hika in the river Vipasa. The Vahikas are the offspring of those two Pishacas. They are not creatures created by the Creator. Being of such low origin, how can they be conversant with the duties ordained in the scriptures? The Karashakas, the Mahishakas, the Kalingas, the Keralas, the Karkotakas, the Virakas, and other peoples of no religion, one should always avoid.' Even thus did a Rakshasa woman of gigantic hips speak unto a Brahmana who on a certain occasion went to that country for bathing in a sacred water and passed a single night there. The regions are called by the name of Arattas. The people residing there are called the Vahikas. The lowest of Brahmanas also are residing there from very remote times. They are without the Veda and without knowledge, without sacrifice and without the power to assist at other's sacrifices. They are all fallen and many amongst them have been begotten by Shudras upon other peoples' girls. The gods never accept any gifts from them. The Prasthalas, the Madras, the Gandharas, the Arattas, those called Khasas, the Vasatis, the Sindhus and the Sauviras are almost as blamable in their practices.
