The Guru Granth Sahib is treated as a living Guru rather than a book about one: it is installed on a raised platform under a canopy, attended with a whisk, put to rest in its own room at night, and transported with ceremony. Its contents are notably plural — alongside the Sikh Gurus it includes hymns by Hindu and Muslim saints, among them Kabir, Namdev, and the Sufi Farid, all preserved as scripture. Guru Arjan compiled it; Guru Gobind Singh sealed it and made it his successor.
