Mahabharata: Pandavas after the War

                                                                  Q. What happened to the Pandavas after the war? As per my information, once their children were murdered, they left for the Himalayas on the path of heaven.

                                                                  Q. Yudhisthira could see outcome of the battle of Kurukshetra only after the battle was over and he was aggrieved very much. But Arjuna was able to foresee the massacre. Is this quality of Arjuna that made him eligible to receive Bhagavad-Gita directly from the Lord even though all the Pandavas are His dear devotees?
