Vali, returning from a demon's cave that Sugriva had sealed thinking him dead, drives Sugriva out and takes his wife Ruma. Rama allies with Sugriva at Rishyamuka. In the first fight he cannot tell the brothers apart; Sugriva returns wearing a garland, and despite Tara's warning Vali fights him again and Rama shoots him from cover. Vali accuses Rama of striking an unengaged foe; Rama answers that he punished Vali under Bharata's law for taking his brother's wife. Vali accepts, commends Angada to him and dies; Sugriva is crowned.

Hanuman leaps the ocean to Lanka, passing the mountain Mainaka, the serpent mother Surasa and the shadow-catcher Simhika, searches the city by night, finds Sita in the Ashoka grove and gives her Rama's ring, then lets himself be caught and burns Lanka with his own tail.
When Lakshmana lies dying on the battlefield of Lanka, Hanuman flies to the Himalaya for four healing herbs, cannot tell them apart, and brings back the whole peak. Tulsidas adds the false hermit Kalanemi and Bharata's arrow over Ayodhya.
At Janaka's court in Mithila no king can lift the bow of Shiva that is Sita's bride-price; the young Rama lifts it, strings it and breaks it in two, and wins Sita. Tulsidas sets it at a crowded contest, and brings in Parashurama, furious at the sound.
On the first night of the exile Rama reaches the Ganga at Shringaverapura, where the Nishada king Guha welcomes him and ferries him across. In Tulsidas the boatman will not let him into the boat until he has washed his feet, in case their dust turns the boat into a woman.
After the war Rama tells Sita before the assembly that he fought for his honour, not for her; she answers him and walks into a pyre, and Agni himself carries her out unburnt; later tellings say the woman in Lanka was only her shadow and the real Sita had waited in the fire.
Cast off by Rama because of what the people said, Sita bears twin sons in Valmiki's hermitage; when the boys sing the Ramayana at Rama's sacrifice and she is called to swear her purity again, she asks the Earth to take her, and the ground opens.
A girl born of the three great goddesses waits on Trikuta mountain for Rama's promise; in the Kali age she feeds Pandit Shridhar's village, flees the Tantric Bhairon Nath up the mountain, hides nine months in a cave, beheads him at the mouth of her own, and grants him that her pilgrims must also visit him.
Ravana and his brothers Kumbhakarna and Vibhishana perform austerities at Gokarna for ten thousand years.
