While the Guru Granth Sahib is an unquestioned scripture in Sikhism, another important religious text, the Dasam Granth, does not enjoy universal consensus, but is considered a secondary scripture by many Sikhs. Adi Granth The Ādi Granth was compiled primarily by Bhai Gurdas under the supervision of Guru Arjan between the years 1603 and 1604. It is written in the Gurmukhī script, which is a descendant of the Laṇḍā script used in the Punjab at that time. The Gurmukhī script was standardised by Guru Angad, the second guru of the Sikhs, for use in the Sikh scriptures and is thought to have been influenced by the Śāradā and Devanāgarī scripts. An authoritative scripture was created to protect the integrity of hymns and teachings of the Sikh Gurus, and thirteen Hindu and two Muslim bhagats of the Bhakti movement sant tradition in medieval India. The thirteen Hindu bhagats whose teachings were entered into the text included Ramananda, Namdev, Pipa, Ravidas, Beni, Bhikhan, Dhanna, Jaidev, Parmanand, Sadhana, Sain, Sur, Trilochan, while the two Muslim bhagats were Kabir and Sufi saint Farid. However, the bhagats in context often spoke of transcending their religious labels, Kabir often attributed to being a Muslim states in the Adi Granth, "I am not Hindu nor Muslim." The Gurus following on this message taught that different methods of devotion are for the same infinite God. Guru Granth Sahib The Guru Granth Sahib is the holy scripture of the Sikhs, and is regarded as the living Guru. Compilation The Guru Granth started as a volume of Guru Nanak's poetic compositions. Prior to his death, he passed on his volume to Guru Angad (Guru 1539–1551). The final version of the Gurū Granth Sāhib was compiled by Guru Gobind Singh in 1678. It consists of the original Ādi Granth with the addition of Guru Tegh Bahadur's hymns. The predominant bulk of Guru Granth Sahib is compositions by seven Sikh Gurus – Guru Nanak, Guru Angad, Guru Amar Das, Guru Ram Das, Guru Arjan, Guru Teg Bahadur and Guru Gobind Singh. It also contains the traditions and teachings of thirteen Hindu Bhakti movement sants (saints) such as Ramananda, Namdev among others, and two Muslim saints namely Kabir and the Sufi Sheikh Farid. The text comprises 6,000 śabads (line compositions), which are poetically rendered and set to rhythmic ancient north Indian classical music. The bulk of the scripture is classified into sixty rāgas,
