Sarg 8 - Raakshas Leave Lankaa

When Vishnu was killing running Raakshas, Maalyavaan came and stood in front of Vishnu and said - "Vishnu, Aren't you ashamed of killing running Raakshas? This will not bring you any glory. If you want to show your bravery, then come and fight with me, I am standing here." Seeing Maalyavaan standing before Him, Vishnu said - "Maalyavaan, Because of your evil actions we Devtaa have decided to kill you. That is why even if you go to Rasaatal, we will kill you."

Maalyavaan threw a power on Vishnu's chest. It entered His chest, but He pulled it out and threw back on Maalyavaan. It broke Maalyavaan's armor and he fell on the ground unconscious. But soon he stood up as healthy as ever in front of Bhagvaan. Then he threw his trident on Vishnu and hit His chest with his fist. He hit Garud also, but Garud shook his wings and pushed him aside. Seeing Maalyavaan in this condition, Maalee ran away to Lankaa. Maalyavaan also became restless, so he also ran away to Lankaa."

Agastya Muni further said - "Hey Raam, Many warriors were killed in this great terrible war. [and since Raakshas could not defeat Bhagvaan] They all ran away to Paataal along with their wives abandoning Lankaa. All this account is of those inhabitants who were living before Vaishravan (Kuber). Whatever Raakshas you killed, were not of Katankataa Vansh. The previous Raakshas were more powerful than Raavan. They could not be killed by anybody else than Vishnu Bhagvaan Himself.

You are the incarnation of Naaraayan and have come on Prithvi to kill the descendents of Pulastya Rishi. As and when Dharm decreases on Prithvi you incarnate on Prithvi to protect Dharm. Hey Raam, Now I tell you about Pulastya Vansh, its descendent Raavan and his sons.

So after Maalyavaan and Sumaalee had left for Paataal, Vaishravan (Kuber) made Lankaa as his capital and started living there comfortably.
