(Also: Duru Granth Sahib) Adi Granth means literally the “First Book.” For Sikhs, the three thousand hymns (shabads) contained within its pages are the Word of God. Before the death of Guru Gobind Singh in 1708, he invested the Guruship not in a human successor, but in the scripture itself. Hence, as the most reverend (Sahib) fully authoritative spiritual guide (Guru), the book is also known as the Guru Granth Sahib.
