Mbh 12.71.2a

"'Bhishma said, "I shall recite, O king, those eternal duties in brief, for if I were to mention them in detail, I would never attain to their end. Thou shouldst worship those Brahmanas that are devoted to their duties, possessed of learning, regular in worshipping the gods, observant of high vows, and endued with other accomplishments, when they come to thy abode, and employ them in officiating in thy sacrifices. With thy priest accompanying thee, thou shouldst rise up when they approach, and touch and worship their feet, and do every other act that is necessary. Doing these acts of piety and discharging other acts that are for thy own good, thou shouldst (by presents) cause those Brahmanas to utter benedictions on thee for the success of thy purposes. Endued with sincerity, and wisdom and intelligence, O Bharata, thou shouldst adopt truth and avoid lust and wrath. That foolish king who pursues Profit without driving away lust and wrath, fails to acquire virtue and ultimately sacrifices Profit as well. Never employ those that are covetous and foolish in matters connected with Pleasure and Profit. Thou shouldst always employ in all thy acts those that are free from covetousness and possessed of intelligence. Stained with lust and wrath and unskilled in the transaction of business foolish persons, if vested with authority in matters of Profit, always oppress the people by diverse contrivances productive of mischief. With a sixth part upon fair calculation, of the yield of the soil as his tribute, with fines and forfeitures levied upon offenders, with the imposts, according to the scriptures, upon merchants and traders in return for the protection granted to them, a king should fill his treasury.[226] Realising this just tribute and governing the kingdom properly the king should, with heedfulness, act in such a way that his subjects may not feel the pressure of want.
