The Mission, inspite of its various difficulties and handicaps responded to this call of spreading the light of knowledge and started two educational institutions: one at Along in Siang District in July 1966 and the other at Narottam Nagar in Tirap District in July 1971. It also started a modern hospital at Itanagar in 1979.

Why Ramakrishna Mission came to Tirap of all the places of Arunachal Pradesh is not clear. There may be two reasons: First, Shri K. A. A. Raja, the then Adviser to the Governor of Assam was a lover of Tirap and very much interested in the development of this district. Secondly, even in those days, as early as 1970s, when modern education and thought were unknown in this remote part, Shri Dangwang Lowangdong, Chief of Namsang, correctly understood the importance of modern education which would make his people come at par with others without changing their faith and customs. For this purpose he donated 250 acres of land from the Namsang forest area to the Ramakrishna Mission.
