Bhai Teja Singh hazuria (1879 - 1922), also known as Babu Teja Singh Maingan, a noted Sikh preacher and social reformer, was the son of Bhai Lakhmi Das, a Sahajdhari Sikh of the village of Maingan in Jehlum district, now in Pakistan. After his early education in the village gurdwara, he studied at the Mission High School at Rawalpindi and later joined government service as a storekeeper in the Supply Department. He came in contact with a holy man, Sant Murii Das, under whose influence he resigned his job to devote himself to religious pursuits. He first reorganized the Singh Sabha in his own village and started preaching under its auspices the ideals of Sikh reform.
