Explanation:

The Guru Granth Sahib is the central holy religious scripture of Sikhism, regarded by Sikhs as the final, sovereign and eternal Guru following the lineage of the ten human gurus of the religion.

The Adi Granth, its first rendition, was compiled by the fifth guru, Guru Arjan Dev Ji. Its compilation was completed on 29 August 1604 and first installed inside the Golden Temple in Amritsar on 1 September 1604.

 Baba Buddha was appointed the first Granthi of the Golden Temple. Shortly afterwards Guru Hargobind Sahib Ji added Ramkali Ki Vaar. Later, Guru Gobind Singh Ji, the tenth Sikh guru, added hymns of Guru Tegh Bahadur to the Adi Granth and affirmed the text as his successor.

The text consists of 1,430 angs (pages) and 5,894 shabads (line compositions), which are poetically rendered and set to a rhythmic ancient north Indian classical form of music.

The bulk of the scripture is divided into 31 main ragas, with each Granth raga subdivided according to length and author. The hymns in the scripture are arranged primarily by the ragas in which they are read. The Guru Granth Sahib is written in the Gurmukhi script in various languages including Punjabi, Lahnda, regional Prakrits, Apabhramsa, Sanskrit, Hindi languages (Braj Bhasha, Bangru, Awadhi, Old Hindi), Bhojpuri, Sindhi, Marathi, Marwari, Bengali, Persian and Arabic.
