The heart of Adi Dharma in Punjab Province was Bengal's Adi Brahmo Samaj legend Pundit Nobin Chunder Roy. The Punjab Brahmo Samaj under his influence favoured Hindi language as against Punjabi actuated by nationalistic considerations. He looked upon Hindi as the national language of India and wanted it to be the foundation for the edifice of Indian nationality. He was the founder of Oriental College Lahore and also its principal. He was the first Asst. Registrar of Punjab University, and one of its Fellows. He was Secretary of the Stri Siksha Sabha fighting against heavy odds to establish girls schools. He was one of the most active members of the Anjumani Punjab, afterwards becoming its Secretary and renamed it as Jnan Vistarini Sabha engaging 8 Pundits to translate various works. To spread reform among the backward people of Punjab he published various newspapers in Punjabi,Urdu and Hindi and the highly controversial "Widow Remarriage Advertiser" in English. For the depressed classes he started a night school and the Chamar Sabha. His doors were open to all helpless and the poor. After Navin Chandra Rai left the Punjab (shifting to Agra) in course of his service, initiation into Adi Dharm was given to castes other than Brahmin or Pandit by his successors - a few of whom were Sikh. As a result many Sikhs also joined Adi Dharm in large numbers relying on the Mulmantra of Sikhism ie. Japuji Sahib which begins as Ik Onkar Sat Naam Karta Purakh .. translated as "There is only one God His name is Truth He is the creator.."
