The Ramayana is an ancient Hindu text about Rama, an incarnation of the God Vishnu. It tells the story of the righteous prince Rama and his rescue of his wife Sita after her abduction by the demon king Ravana. I am sorry, we do not have this in Hindi or Kannada. They might be available at archive.org.
This version of Ramayana is retold in English by C. Rajagopalachari and edited by Jay Mazo, American Gita Society.
