Illuminated Guru Granth folio with nisan (Mool Mantar) of Guru Gobind Singh. Collection of Takht Sri Harimandir Sahib, Patna.

The Guru Granth Sahib (Punjabi: ਗੁਰੂ ਗ੍ਰੰਥ ਸਾਹਿਬ, gurū grantha sāhiba) – Granth is Punjabi for book; Sahib is Hindi meaning master, from Arabic, meaning companion, friend, owner, or master – is the holy scripture of the Sikh and Ravidasi faiths.

In the Sikh view it is considered to be more than just a holy book. The Sikhs treat this Granth (holy book) as a living Guru. The holy text spans 1430 pages and contains the actual words spoken by the Sikh Gurus and various other Saints from other religions including Hinduism, Islam, the Kabirpanthi religion and the Ravidasi religion.

The Adi Granth is often used to refer to the Guru Granth Sahib. The Adi Granth only forms the portion of the Granth which Guru Arjan compiled in 1604. This term is often used interchangeably so it is important to note the context within which it is used. The Granth was made a guru by the last of the living Sikh Masters, Guru Gobind Singh in 1708.

The holy text comprises over 5000 Shabhads or hymns which are poetically constructed; and set to classical form of music rendition Ragas; can be set to predetermined musical Talas (rhythmic beats) and have a definite message for the whole of humanity.
