Editions

In 1604, the first edition of the Sikh scripture, Adi Granth, was complete and officially approved by Guru Arjan. It was installed at the Golden Temple, with Baba Buddha as the first granthi or reader. No hymns were added by Guru Hargobind, Guru Har Rai and Guru Har Krishan. In the Sikh tradition, Guru Hargobind is credited for adding the rāga tunes for nine out of 22 Vars. The hymns of IX Guru Tegh Bahadur, after his beheading in Delhi, were added to the scripture by his son and successor Guru Gobind Singh.

In 1704 at Damdama Sahib, during a one-year respite from the heavy fighting with the Mughal Emperor Aurangzeb, Guru Gobind Singh and Bhai Mani Singh added the religious compositions of Guru Tegh Bahadur to the Adi Granth to create the final edition, called the Guru Granth Sahib. Prior to Guru Gobind Singh, three versions of the Adi Granth pothi with minor variations were in circulation at Sikh shrines across the Indian subcontinent. In addition, several unauthorized versions were in circulation, issued by sects founded by one of the sons or relatives of earlier Sikh Gurus such as Prithi Chand, Guru Arjan's elder brother. Guru Gobind Singh issued the definitive final edition that included the hymns of his father, and closed the canon. This manuscript is called the Damdama bir, and a 1707 rare copy of this manuscript is now preserved at the Toshakhana in Nanded, Maharashtra.

The compositions of Guru Gobind Singh were not included in the Guru Granth Sahib and set into the Dasven Padsah ka Granth, which is more popularly known as the Dasam Granth. The compilation and release of this definitive edition of the latter was completed by Bhai Mani Singh.
