Mbh 12.17.1a

"'Yudhishthira said, "Discontent, heedless attachment to earthly goods, the absence of tranquillity, might, folly, vanity, and anxiety,--affected by these sins, O Bhima, thou covetest sovereignty. Freed from desire, prevailing over joy and grief and attaining to tranquillity, strive thou to be happy. That peerless monarch who will govern this unbounded earth, will have but one stomach. Why dost thou then applaud this course of life? One's desires, O bull of Bharata's race, are incapable of being filled in a day, or in many months. Desire, which is incapable of gratification, cannot, indeed, be fitted in course of one's whole life. Fire, when fed with fuel, blazeth forth; when not so fed, it is extinguished. Do thou, therefore, extinguish with little food the fire in thy stomach when it appears. He that is bereft of wisdom seeks much food for his stomach. Conquer thy stomach first. (Thou shalt then be able to conquer the Earth). The earth being conquered, that which is for thy permanent good will then be won by thee. Thou applaudest desires and enjoyments and prosperity. They, however, that have renounced all enjoyments and reduced their bodies by penances, attain to regions of beatitude. The acquisition and preservation of kingdom is attended with both righteousness and unrighteousness. The desire for them exists in thee. Free thyself, however, from thy great burthens, and adopt renunciation. The tiger, for filling one stomach of his, slaughters many animals. Other animals destitute of strength and moved by covetousness live upon the tiger's prey.[47] If kings, accepting earthly possessions, practise renunciation, they can never have contentment. Behold the loss of understanding that is noticeable in them. As a matter of fact, however, they who subsist on leaves of trees, or use two stones only or their teeth alone for husking their grain, or live upon water only or air alone, succeed in conquering hell.
