Mbh 2.54.1a

“Duryodhana said,--‘He that is devoid of intellect but hath merely heard of many things, can scarcely understand the real import of the scriptures, like the spoon that hath no perception of the taste of the soup it toucheth. Thou knowest everything, but yet confoundest me. Like a boat fastened to another, thou and I are tied to each other. Art thou unmindful of thy own interests? Or, dost thou entertain hostile feeling towards me? These thy sons and allies are doomed to destruction, inasmuch as they have thee for their ruler, for thou describest as attainable in the future what is to be done at the present moment. He often trippeth whose guide acts under the instructions of others. How then can his followers expect to come across a right path? O king, thou art of mature wisdom; thou hast the opportunity to listen to the words of old, and thy senses also are under thy control. It behoveth thee not to confound us who are ready to seek our own interests. Vrihaspati hath said that the usage of kings are different from those of common people. Therefore kings should always attend to their own interests with vigilance. The attainment of success is the sole criterion that should guide the conduct of a Kshatriya. Whether, therefore, the means is virtuous or sinful, what scruples can there be in the duties of one’s own order? He that is desirous of snatching the blazing prosperity of his foe, should, O bull of the Bharata race, bring every direction under his subjection like the charioteer taming the steeds with his whip. Those used to handling weapons say that, a weapon is not simply an instrument that cuts but is a means, whether covert or overt, that can defeat a foe. Who is to be reckoned a foe and who a friend, doth not depend on one’s figure or dimensions. He that paineth another is, O king, to be regarded a foe by him that is pained. Discontent is the root of prosperity. Therefore, O king, I desire to be discontented.
