"In adopting the Hindi as the National tongue of Hindudom no humiliation or any invidious distinction is implied as regards other provincial tongues. We are all as attached to our provincial tongues as to Hindi and they will all grow and flourish in their respective spheres. In fact some of them are today more progressive and richer in literature. But nevertheless, taken all in all the Hindi can serve the purpose of a National Pan-Hindu language best. It must also be remembered that the Hindi is not made a National Language to order. The fact is that long before either the English or even the Moslems stepped in India the Hindi in its general form had already come to occupy the position of a National tongue throughout Hindustan. The Hindu pilgrim, the tradesman, the tourist, the soldier, the Pandit travelled up and down from Bengal to Sind and Kashmere to Rameshwar by making himself understood from locality to locality through Hindi. Just as the Sanskrit was the National Language of the Hindu intellectual world even so Hindi has been for at least a thousand years in the past the National Indian Tongue of the Hindu community..... "By Hindi we of course mean the pure "Sanskrit Nistha" Hindi, as we find it for example in the " Satyartha Prakash " written by Maharsi Dayananda Saraswati. How simple and untainted with a single unnecessary foreign word is that Hindi and how expressive withal ! It may be mentioned in passing that Swami Dayanandaji was about the first Hindu leader who gave conscious and definite expression to the view that Hindi should be the Pan-Hindu National language of India.
