The Gurū Granth Sāhib, also known as the Adi Sri Granth Sahib Ji is the principal sacred scripture of Sikhism. Sikhs consider it not only their holy book, but also their eternal living spiritual leader (Guru.)
The Granth Sahib has its origins in the Adi Granth, a book compiled by Guru Arjan Dev (1563–1606,) the fifth Sikh guru. In addition to the teachings of the first five gurus, he combined hymns and religious poetry.
Guru Gobind Singh, the tenth Sikh guru, finalized the Adi Grath with additional hymns and teachings written by his predecessors. Before his passing, Guru Gobind Singh advised the Sikh community to regard the Granth as their subsequent guru, thus ending the lineage of Sikh gurus. The Adi Granth thus became the Guru Granth Sahib.
At Sikh temples (gurdwaras,) the Granth Sahib is deferentially placed on a throne in the front of the congregational worshippers. It is positioned under a canopy, protected with a blessed piece of fine textile, and held with the utmost respect.
Through loving devotion, their ego evaporates.
