Such a consummation may come to pass, if our king proveth not unwise or procrastinating. Thou art, however, virtuous. Verily the deceitful should be destroyed by deceit. To slay the deceitful by deceit, is not regarded as sinful. O Bharata, it is, also said by those versed in morality that one day and night is, O great prince, equal unto a full year. The Veda text also, exalted one, is often heard, signifying that a year is equivalent to a day when passed in the observance of certain difficult vows. O thou of unfading glory, if the Vedas are an authority with thee, regard thou the period of a day and something more as the equivalent of thirteen years. O represser of foes, this is the time to slay Duryodhana with his adherents. Else, O king, he will beforehand bring the whole earth obedient to his will. O foremost of monarchs, all this is the result of thy addiction to gambling. We are on the verge of destruction already, in consequence of thy promise of living one year undiscovered. I do not find the country where, if we live, the wicked-minded Suyodhana may not be able to trace us by his spies. And finding us out, that wretch will again deceitfully send us into such exile in the woods. Or if that sinful one beholdeth us emerge, after the expiry of the pledged period of non-discovery, he will again invite thee, O great king, to dice, and the play will once more begin. Summoned once more, thou wilt again efface thyself at dice.
