Arjun's sharp arrows, Bheem's mighty power, Yudhister's righteousness, Nakul and Sahadev's dexterity and Krishna's wisdom helped the Pandavas win the bloody war at Kurukshetra. But the irony was such that all except Yudhister could reach heaven. Mahabharata with its great fratricidal war has all the excellent elements of drama. It has complex characters and a layered narrative. That is why the Mahabharata has been open to interpretations and retellings.
