In his letter to Ramdhari Sinha ‘Dinkar’ dated 10 September 1956, Nehru wrote: I am convinced that real mass progress in India can only be made through our languages and not through a foreign language. I am anxious to prevent a new caste system being perpetuated in India—an English-knowing caste separated from the mass of our people… I cannot conceive of English being the principal medium of education in India in the future. That medium has to be Hindi or some other regional language.
