The Guru Granth Sahib Ji is the holy scripture of Sikhism, regarded by Sikhs as the final and eternal Guru following the lineage of the ten human gurus of the religion. The Guru Granth Sahib Ji is 1,430 pages (Angs) of sacred teachings and songs. In addition to six of the Sikh Gurus, there are compositions from saints from different religions, places, and times.
The Adi Granth was the first version of the holy book. It was compiled by the fifth guru, Guru Arjan, to keep an official and accurate record of all the hymns composed by previous Gurus. The Guru Granth Sahib contains hymns of the following Sikh Gurus: Guru Nanak, Guru Angad, Guru Amar Das, Guru Ram Das, Guru Arjan and Guru Teg Bahadur. Additionally, the scripture contains verses of thirteen Hindu poets and two Muslim saints.
When Guru Gobind Singh Ji passed in 1708, He passed the Guruship to the Guru Granth Sahib ji. This ended the time of the physical Gurus of the Sikhs, and it was declared that the word of Waheguru, embodied in the Siri Guru Granth Sahib, was to be Guru for all time.Thus, the Word of God, manifested as Guru in Nanak, and passed through the ten incarnations of Guru, was now returned to its form as the Word – the Bani, the Shabad. This began the reign of the Shabad Guru, itself, as the Spiritual Light and Guide for the Sikh community.
