History of Guru Granth Sahib ji
Guru Arjan Dev ji, the fifth Sikh Guru compiled the original version of Guru Granth Sahib ji. Guru Arjan Dev ji felt that the Sikhs needed authentic compilation of the hymns of their gurus. Thus Guru ArjanDev ji started the collection of original verses of all the Gurus. He sent reliable Sikhs like Bhai Piara ji, Bhai Gurdas ji and Baba Buddha ji across the country in search of original manuscripts. Guru Arjan Dev ji travelled to Goindwal, Khadur and Kartarpur to visit the families of the previous Gurus. Guru Arjan Dev ji collected original manuscripts of the Gurus from Mohan ji (son of Guru Amar Das ji), Datu ji (son of Guru Angad ji) as well as Sri Chand ji (son of Guru Nanak ji).
Compilation and Contents of the Guru Granth Sahib
Many of Guru Nanak ji’s hymns and prayers were preserved and complied by Guru Angad ji and Guru ArjanDev refuse to expunge the so-called offensive text or pay the fine. Guru Arjan Dev ji was against making alterations in the hymns as required by Jahangir and instead preferred a martyr’s death. This led to his execution. The Adi Granth was completed in 1604 and installed in the Golden Temple. In 1708, Adi Granth became Sri Guru Granth Sahib Ji, the Eternal Guru of Sikhs as was declared by Guru Gobind Singh Ji. After Guru Gobind Singh ji’s martyrdom in 1708, Baba Deep Singh ji and Bhai Mani Singh ji prepared many copies of the Sri Guru Granth Sahib ji for distribution.
