Gurbani is a Sikh term, very commonly used by Sikhs to refer to various compositions by the Sikh Gurus and other writers of Guru Granth Sahib. In general, hymns in the central text of the Sikhs, the Guru Granth Sahib, are called Gurbani. Among Amritdhari Sikhs, a few texts from Dasam Granth which are read as Nitnem, like Tav-Prasad Savaiye and Chaupai, are also considered Gurbani. In Adi Granth, Gurbani is a sound which comes directly from the Supreme and the text is a written form of the same in worldly language and scripts. It is also called Guru's Bani.
