"Dhritarashtra said, "What Vidura told me at the time of the game at dice, 'If thou seekest, O king, to vanquish the Pandavas (at dice), then certainly a terrible blood-shed ending in the destruction of all the Kurus will be the result,' I think it is about to be realised. As Vidura told me of old, without doubt a terrible battle will take place, as soon as the pledged period of the Pandavas expireth.'"
