Mbh 8.45.1b

The Kauravas with the Pancalas, the Salwas, the Matsyas, the Naimishas, the Koshalas, the Kasapaundras, the Kalingas, the Magadhas, and the Cedis who are all highly blessed, know what the eternal religion is. The wicked even of these various countries know what religion is. The Vahikas, however, live without righteousness. Beginning with the Matsyas, the residents of the Kuru and the Pancala countries, the Naimishas as well and the other respectable peoples, the pious among all races are conversant with the eternal truths of religion. This cannot be said of the Madrakas and the crooked-hearted race that resides in the country of the five rivers. Knowing all these things, O king, hold thy tongue, O Shalya, like one deprived of utterance, in all matters connected with religion and virtue. Thou art the protector and king of that people, and, therefore, the partaker of sixth part of their merits and demerits. Or perhaps, thou art the partaker of a sixth part of their demerits only, for thou never protectest them. A king that protects is a sharer in the merits of his subjects. Thou art not a sharer in their merits. In days of yore, when the eternal religion was reverenced in all countries, the Grandsire, observing the practices of the country of the five rivers, cried fie on them. When even in the Krita age, Brahman had censured the practices of those fallen people of evil deeds who were begotten by Shudras on others' wives, what would you now say to men in the world? Even thus did the Grandsire condemn the practices of the country of the five waters. When all people were observant of the duties of their respective orders, the Grandsire had to find fault with these men. Thou shouldst know all this, O Shalya. I shall, however, again speak to thee. A Rakshasa of the name of Kalmashapada, while plunging in a tank, said, 'Eleemosynation is a Kshatriya's dirt, while the non-observance of vows is a Brahmana's dirt.
