[1][2] Samundri was born to Deva Singh and Nand Kaur on 20 February 1882 at Rai Ka Burj in Tarn Taran tehsil, Amritsar district, Punjab.
[2] He served in the British Indian Army for three-and-a-half years, reaching the rank of Dafadar (junior commissioned officer) in the 22nd Cavalry.
[2] He was arrested again on 13 October 1923 due to participating in a joint SGPC-Akali campaign to restore the recent reposed Maharaja Ripudaman Singh to the throne of Nabha State after his excommunication by the British.
[2] The British declared that the SGPC and Akali Dal were illegal entities, thus fifty-nine leaders of both organizations were arrested, including Teja Singh, being charged with "waging war against the King".
[2] The building that houses the headquarters of the SGPC within the Golden Temple complex in Amritsar is named Teja Singh Samundri Hall after him.
