A leading soldier of Indian independence struggle, a front-ranking General of Akali Movement, a leading educationist, a formidable journalist, a great patriot and a dedicated Sikh to the core, Master Lyallpuri was the one who had given birth to Akali Movement and Shiromani Akali Dal, reared them up and brought them to adulthood. All through his life, this Dervesh soldier believed in simple living and result-oriented actions. He had played a very crucial role in awakening and organizing the dormant Sikh community into a powerful force which played a leading role in India's struggle for independence as well as for the Sikh Reform Movements of early twenties.
