<P> The first to die was Draupadi; she was imperfect because she preferred Arjuna over her other husbands . Then it was Sahadeva, imperfect because he was smug about his knowledge . He was followed by Nakula, imperfect because he was arrogant about his good looks . Then fell Arjuna, imperfect because he was always jealous of other archers . Next was Bhima, imperfect because he was a glutton . Only the eldest Pandava, Yudhisthira, reached the door of Swarga Loka, carried on Lord Indra's chariot . On reaching Heaven he did not find either his virtuous brothers or his wife Draupadi . Instead he saw Karna, Bhishma, Dronacharya etc. and their sons . </P> <P> He wanted an explanation from Lord Yama, the lord of death . Lord Yama explained that the Kauravas had been allowed into heaven because they died as warriors on the battlefield . This earned them so much merit and credit that it wiped out all their debts . Yudhisthira demanded to know where his brothers and his wife were . He was then taken to hell . Lord Yama explained that they were experiencing the reactions of their actions but it was temporary . Once the debt had been repaid, they would join them in Swarga . Yudhisthira loyally met his brothers, but the sight and sound of gore and blood horrified him . Though initially he was tempted to flee, he mastered himself and remained after hearing the voices of his beloved brothers and Draupadi calling out to him, asking him to stay with them in their misery . Yudhisthira decided to remain, ordering the divine charioteer to return . He preferred to live in hell with good people than in a heaven of his enemies . Eventually this turned out to be another illusion to test him . </P> <P> Krishna, being a well wisher of the Pandavas, helped them in various ways during the time of their ordeals . </P> <P> The first three of the Pandavas were the sons of Kunti, a Yadava and Pandu's first wife . The younger two were the sons of Madri, Pandu's second wife . Since Pandu had been cursed to die if ever he had intercourse with a woman, the actual fatherhood of the children is traditionally attributed to various gods, in virtue of a boon that Kunti had received from the sage Durvasa and had transferred to Madri . Thus - </P>
