Guru Granth Sahib is the eponymous central text of the Sikh religion, believed to be compiled by the final and last eternal guru of the faith. The Guru Granth Sahib is believed by Sikhs to be the ultimate spiritual guide for all of humanity and is based on two precepts. The text is believed to be a living guru and contains all answers regarding religion and morality. Each "Ang" is a musical setting for a prayer, and the YouTube video contains nearly the entire content of the text.
