In some versions, Lava and Kusha capture the horse of the sacrifice and defeat Rama's brothers and their army and when Rama came to fight with them, Maharishi Valmiki intervened and then Sita discloses to their sons that their father is Lord Rama and Valmiki told the children that through a song they have to recite the story of holy Ramayana to the people of Ayodhya that how Sita sacrifices even Gold Lanka (Ravana Mahal) to wash away the spoilt image of Sita from Ayodhya people.
