Lord Rama then crossed the ocean with His monkey army and killed all the demons under Ravana's leadership. He only spared Vibhisana, because Vibhisana was a devotee and favorable to Rama. Ravana and all his sons were killed. When Sita was presented to Rama, He said, "I will not take Sita with Me. I am a ksatriya king. I did not come here to take Sita back. I came to destroy all of Lanka because Ravana kidnapped Her, but because She was in the house of Ravana I cannot accept Her." He ordered Laksmana to build a fire in order to test Her chastity. Sita prayed, "O Agnideva, O demigod of fire, I will enter the fire, and if I am pure I'll not be burned." She entered the fire and Agnideva came out with Her and said, "She is pure." The Air-god, the demigod of air, then appeared and said, "I am everywhere. I know Sita is pure."
Rama then took Sita and returned to Ayodhya with His new associates like Vibhisana and Hanuman, and He was given the kingdom on that day, Rama Navami, which happened to be the day He was exiled and also happened to be the same day as the anniversary of His birth. The residents of Ayodhya performed an abhiseka ceremony to install Him as king.
Sita had a desire to see the rsis and maharsis – to give Her merciful darsana. In the meantime, some of the inhabitants of Ayodhya began to say that although She was not pure, Rama still took Her back. They concluded, "This is a very bad thing."Rama then sent Sita into exile, although She was pregnant at that time. She went to the asrama of Valmiki, where She gave birth to two sons named Lav and Kush. Her sons were very strong and powerful.
