This is a monumental work on the Sikh Religion, firstever published in 1909. The purpose of the author was to introduce the lofty ideals of the Gurus to the western world in their true spirit. Hence he translated the Sikh Scripture into English with the help of the renowned Sikh scholars of the times including Bhai Khan Singh Nabha.
