The Installation of the Guru Granth in 1604 was a pivotal event where Guru Arjan Dev, the fifth Sikh Guru, completed the sacred scripture and placed it in the Harmandir Sahib (Golden Temple) in Amritsar. This act marked the elevation of the scripture as the eternal, living Guru for Sikhs, symbolizing that divine wisdom resides in the eternal Word, not a human. The installation was also marked by specific rituals, and today the Guru Granth is treated with great reverence in every gurdwara.
