Gurbani refers to the sacred writings and compositions in Sikhism. It is the term used to describe the verses, hymns, and teachings found in the Guru Granth Sahib, which is the central religious scripture of Sikhism. Gurbani is written in Gurmukhi script and consists of hymns and poems composed by Sikh Gurus, saints, and other spiritually enlightened individuals from different religious backgrounds.

The Guru Granth Sahib is not just a collection of writings but is regarded by Sikhs as the eternal Guru, embodying the spiritual guidance and wisdom for the Sikh community. It contains the teachings and experiences of Sikh Gurus, including Guru Nanak Dev Ji, the founder of Sikhism, and his successors, up to Guru Gobind Singh Ji, the tenth Guru. The writings also include contributions from other Bhakti movement saints and poets like Kabir, Namdev, Ravidas, and others.

Gurbani emphasizes the oneness of God, the importance of selfless service, devotion, and the pursuit of truth. Sikhs regard Gurbani as the ultimate source of spiritual wisdom and guidance, and it is recited, sung, and studied in Sikh congregations, known as Gurdwaras, and in the daily lives of Sikh individuals.
