'New Literature' is a misnomer for the wealth of the Indian Literary tradition. How does G. N. Devy explain this?

According to the essayist, the tribal Literature should not be called 'New Literature' as this has been in existence for many years. The songs and stories of the tribals have been transmitted orally and as these have not been written down so many people have been unaware of them. The essayist contradicts the views of the western literary critics who have termed tribal literature as 'New Literature'. He says that there is nothing new in this, what might be new is the present attempt to see imaginative expression in tribal language not as folklore but as literature and to hear tribal speech not as a dialect but as a language.
