The Uttara Kanda, the last book of the Ramayana, for instance, was later added class to the original poem. It has the story of Rama 's killed Shambuka, despite being a knowledgeable person because he was a non-Brahmin. This story was planted in order to propogate the Brahminical view of Sri Rama. To counter these attempts by the dominant class, folk wisdom every few centuries tried to rescue these poems from the caste structure. In a way, the history of the translations of the Ramayana and the Mahabharata in India effectively reflects the history of the caste conflict in India. As a result, while there were several Ramayanas and Mahabharatas in the country such as the Mahabharata of the Bhils, the Bhandarkar Institute standardized it and produced the Critical Version, a canonical text, with the other versions shown as variations.
