Rama severed both of Dushana's arms with his arrows, and the demon fell lifeless to the ground. The three-headed demon Trishira, a son of Ravana and Dhanyamalini, shot several arrows at Rama. Rama told him that the arrows felt like flowers patting his body. He then shot three arrows at Trishira, which severed all three of Trishira's heads, killing him. Rama then used a powerful arrow gifted by Maharshi Agastya to pierce Khara's heart.
He then shot thousands of crescent-shaped arrows and decimated the demon army.
The gods in heaven were pleased by the deaths of Khara and Dushana and showered flowers on Rama. Lakshmana and Sita came out of hiding. Maharshi Agastya and various other sages congratulated Rama on his victory. Sita was glad that her husband was safe and sound.
The sole survivor of the carnage, Akampana, went to Lanka and reported Khara and Dushana's defeat to the Demon King Ravana. "O King, Rama is invincible on the battlefield. He is also greatly devoted to his wife, Sita. So instead of engaging him in direct combat, abduct Sita. He will then die of grief."
Shurpanakha then arrived at Ravana's court, her face still bleeding. "Who has done this to you, Shurpanakha?" thundered Ravana.
"A man called Rama has annihilated your powerful cousins Khara and Dushana, along with their entire army at Janasthana. His brother, Lakshmana, is the one who cut off my nose and ears."
Ravana remembered Rama and Lakshmana from Sita's swayamvara. Shurpanakha described Sita as the most beautiful woman in the world and said that she ought to be Ravana's wife. Consequently, she too incited Ravana to kidnap Sita.
