War with thrisurudu

Khara started to go for the war against Rama.But his army chief,Thrisirudu stooped him.He pleaded that he be sent to foght Rama.When the army chief was there,there was no need for Khara to actually neter the batle field.He would put an end to Rama and clear the minds of demons and their anguish .He would surely kill Rama.Other wise,he would be killed by Rama.He was requesting Khara to stop the war and observe the fight between Rama and Thrisirudu.Khara gave him permission to go and fight Rama.Rama and Thrisirudu fought like hell.It created uproar.Thrisirudu attacked Rama with three arrows directed to his forehead.
Rama made fun of him saying that they were as if he was touched by flowers.Saying so he released arrows directed towards Thrisirudu telling him to taste his arrows.Rama cut off all the three heads of Thrisirudu.
