TEJĀ SIṄGH HAZŪRĪĀ, BHĀĪ (1879-1922), also known as Bābā Tejā Siṅgh Maiṅgaṇ, a noted Sikh preacher and social reformer, was the son of Bhāī Lakhmī Dās, a Sahajdhārī Sikh of the village of Maiṅgaṇ in Jehlum district, now in Pakistan. After his early education in the village gurdwārā, he studied at the Mission High School at Rāwalpiṇḍī and later joined government service as a store keeper in the Supply Department. He came in contact with a holy man, Sant Murlī Dās, under whose influence he resigned his job to devote himself to religious pursuits. He first reorganized the Siṅgh Sabhā in his own village and started preaching under its auspices the ideals of Sikh reform. He reclaimed many from the laxity of belief and practice they had fallen victim to and administered to them the vows of the initiation. He himself had received the baptism at the hands of the venerable Sant Atar Siṅgh. He joined the Chief Khālsā Dīvān and, as a preacher on its cadre, travelled extensively throughout the country. At the famous dīvān at Bakāpur, in Jalandhar district, at which a Muslim family received the rites of the Khālsā Bhāī Tejā Siṅgh was one of the Pañj Piāre or the five chosen who conducted the ceremony.

        Bhāī Tejā Siṅgh was deputed by the Chief Khālsā Dīwān to travel to the South and meet the priest of Takht Sachkhaṇḍ Srī Hazūr Sāhib at Nāndeḍ, who had refused Sardār Sundar Siṅgh Majīṭhīā entry into the inner sanctuary on the ground that he had not been baptized at the shrine. He argued with the Hazūr Sāhib ministers and convinced them that Sikh baptism wherever received had the same sanctity and that no distinction could be made between Sikh and Sikh on the grounds of where the ceremony was performed. From the priests he now had a standing invitation to visit Srī Hazūr Sāhib on the occasion of Holā every year. They addressed him as "Huzūrīā" i.e. one who had been granted the citizenship of Srī Hazūr Sāhib. The word got added as a suffix to his name.

        Besides being a powerful orator and debater, Tejā Siṅgh was a writer. He published five books in Punjabi, namely Sahajdhārī Sikh, Dase Gurū Ikk Rūp San (all ten Gurūs reflected one spirit); Ham Hindu Nahīṅ (We are not Hindus); Khālsā Panth; and Srī Abchalnagar Sāhib de Adbhut Darshan, an account of his pilgrimage to Takht Sachkhaṇḍ Srī Hazūr Sāhib.

        Bhāī Tejā Siṅgh died on 1 January 1922.
