This is one of the earliest commentaries on the text of Guru Granth Sahib. It was prepared by Giani Bachan Singh and reviewed and revised by a group by scholars under the supervision of Pandit Baba Sumer Singh. This commentary was prepared as a rebuttal to the somewhat skewed English translation of the Sikh sacred text by Dr. Earnest trump which was perhaps the first English translation of this text. Since the commentators belonged to the Nirmala Sikh sub-sect, the commentary is written in Hindized diction although the script used it Gurmukh. Since it is one of the earliest commentaries, its interpretation of Gurbani text and idiom is limited and coloured by the vedantic background of the commentator. Later commentaries have given multiple interpretations of the text. Even then, it is pioneering work in the field of commentaries and starts a tradition of exposition and interpretation of the Gurbani text. It occupies a prominent place in the Gurmat literature.
