Sikhs consider the Guru Granth Sahib to be a spiritual guide not only for Sikhs but for all of humanity; it plays a central role in guiding the Sikhs' way of life. Its place in Sikh devotional life is based on two fundamental principles: that the text is the living Guru and that all answers regarding religion and morality can be discovered within it. Its hymns and teachings are called Gurbani or "Word of the guru" and sometimes Guru ki bani or "Word of Guru".
