Mbh 5.29.1d

The following are the duties declared for a Sudra from the olden times. He should serve the Brahmanas and submit to them; should not study; sacrifices are forbidden to him; he should be diligent and be constantly enterprising in doing all that is for his good. The king protects all these with (proper) care, and sets all the castes to perform their respective duties. He should not be given to sensual enjoyments. He should be impartial, and treat all his subjects on an equal footing. The King should never obey the dictates of such desires as are opposed to righteousness. If there be any body who is more praise-worthy than he, who is well-known and gifted with all the virtues, the king should instruct his subjects to see him. A bad (king), however, would not understand this. Growing strong, and inhuman and becoming a mark for destiny’s wrath, he would cast covetous eye on the riches of others. Then comes war, for which purpose came into being weapons, and armour, and bows. Indra invented these contrivances, for putting the plunderers to death. He also contrived armours, and weapons, and bows. Religious merit is acquired by putting the robbers to death. Many awful evils have manifested themselves on account of the Kurus having been unrighteous, and unmindful of law and religion. This is not right, O Sanjaya. Now, king Dhritarashtra with his sons, hath unreasonably seized what lawfully belonged to Pandu’s son. He minds not the immemorial law observable by kings. All the Kurus are following in the wake. A thief who steals wealth unseen and one who forcibly seizes the same, in open day-light, are both to be condemned, O Sanjaya. What is the difference between them and Dhritarashtra’s sons? From avarice he regards that to be righteous which he intends to do, following the dictates of his wrath. The shares of the Pandavas is, no doubt, fixed. Why should that share of theirs be seized by that fool?
