Guru Granth Sahib is the Sikh Scripture. Guru Arjan (1563-1606), compiled the first edition of Guru Granth Sahib, in 1604 C.E. The first volume of Guru Granth Sahib was completed on July 31, 1604 and installed in Darbar Sahib, Amritsar, on August 16, 1604. It was granted the status of the Guru-Eternal on October 6, 1708. Most of its 5867 verses were written by six Sikh Gurus: Guru Nanak, Guru Angad, Guru Amar Das, Guru Ram Das, Guru Arjan and Guru Tegh Bahadur. In spite of such a big number of composers, belonging to different areas and even beliefs, Guru Granth Sahib has homogeneity of thought; and, wherever, in the compositions of the non-Gurus, it could look like creating confusion in the mind of the reader, the Gurus added their own verses to elucidate the point.
