Guru Granth Sahib (also known as the Adi Granth) is the scripture of the Sikhs. No Sikh ceremony is regarded as complete unless it is performed in the presence of Guru Granth Sahib. The Granth was written in Gurmukhi script and it contains the actual words and verses as uttered by the Sikh Gurus.

It is considered the Supreme Spiritual Authority and Head of the Sikh religion, rather than any living person. It is also the only scripture of its kind which not only contains the works of its own religious founders but also the writings of people of other faiths. The living Guru of the Sikhs, the book is held in great reverence by Sikhs and treated with the utmost respect.

Guru Granth Sahib is a book of Revelation. It conveys the Word of the Master through His messengers on earth. It is universal in its scope. The greatness of the Guru Granth Sahib lies not only in its being the Holy Scripture of the Sikhs but also in it being a general scripture available to mankind, intended for everybody, everywhere.
