The ksatriyas used to fight the kings of various dominions and kidnap their beautiful princess-daughters, after conquering their relatives. This system was laudable because the ksatriyas and the princesses would be married only on the basis of the chivalry of the conquering ksatriya. All the young princes of the Yadu dynasty married the daughters of other kings in this way, by chivalrous force, and thus they were conquerors of all the kings of the world. Vidura wanted to impress upon his elder brother that fighting with the Pandavas was fraught with many dangers because they were supported by Lord Krsna, who had conquered, even in His childhood, demons like Kamsa and Jarasandha and demigods like Brahma and Indra. Therefore all universal power was behind the Pandavas.
