Fresh causes of jealousy arose between the cousins. Yudhisthira’s claim to the succession could not be set aside, as the people were all in favour of him; so he was appointed by the blind king, very reluctantly, we may presume, to the office of Yuva-Rajah, or heir-apparent. The Pandavas, elated by their success against the King of Panchala, and confident in themselves, commenced a series of unprovoked attacks upon the neighbouring princes. Of course the Pandavas performed prodigies of valour in these invasions. For example, two of them with a single chariot, “subjugated all the kings of the East backed by ten thousand chariots.” These great achievements inflamed the jealousy of even the blind king to such a pitch that he disclosed his feelings to Kanika, his Brahman counsellor, “well skilled in the science of politics.” As became a sage politician, Kanika advised his master to put the obnoxious Pandavas out of the way as soon as possible. He explained to Dhritarashtra his obvious duty in such a case, and impressed upon his sovereign such important maxims of state policy as the following: “When thy foe is in thy power destroy him by every means, open or secret: Do not show him any mercy although he seeketh thy protection.... If thy son, friend, brother, father or even spiritual preceptor, becometh thy foe, thou shouldst, if desirous of prosperity, slay him without scruples. By curses and incantations, by gift of wealth, by poison, or by deception the foe should be slain. He should never be neglected from disdain.” His counsels fell on only too willing ears. Dhritarashtra was ready to do his _duty_ as thus explained to him, but thought it best to act warily. Duryodhana suggested that the Pandavas should be induced to go to Varanavartha,[63] and there be disposed of.
