Sri Guru Granth Sahib Ji has been standardised to 1430 Angs (pages). For the most part, the Shabads (Guru’s words) are arranged by 31 Raags. A Raag describes the musical scale, structure and how to create a melody. Each Raag reflects a different spiritual mood or tone and is sung at different times of the day. Within each Raag, the Shabads are arranged in chronological order by Guru, followed by the Bhagats (Muslim and Hindu Saints). The first part includes basic Nitnem Banis (Jap Ji Sahib, Rehraas Sahib and Sohila Sahib), Raag section and the other Banis at the end that are not written in the Raags.
