In the aftermath of the commotion caused by the Vanara legions, silence once again returned to mount Prasravana. In the quiet of that moment Rama asked, " Sugriva, how do you know so much of the earth with its countless hills, rivers, mountains and oceans?" And Sugriva replied, "Listen to my story Rama". "Many years ago Dundhubhi the demon came up to the gates of Kishkinda and challenged Vali to battle. But even before Vali could confront him the terror struck monster vanished into a cave. Bidding me to wait out side, Vali went after his enemy. Days, weeks and months passed but of Vali there was no sign. Then one-day streams of blood came gushing out of the mountain cave, followed by cries of agony. Deeming my brother dead, grieving for him I went back to Kishkinda. "As I settled down to ruling the Vanara kingdom, Vali came back! For it was not he who had died but Dundhubhi. Though I immediately returned the kingdom to him with all respect, Vali would neither believe me nor forgive me, but tried to kill me! Trying to save myself I fled Kishkinda with my ministers. Leaping across rivers ravines, over hills and through countless cities I ran! But there seemed to be no escape. It was then that Hanuman reminded me that sage Matanga had cursed Vali with death, if he ever entered his grove, Matanga vana. So after having run all over the world, that is where we found refuge and that is how I know every nook and corner of the earth!"
