Guru Granth Sahib Ji is known as the 11th and the last guru of Sikhs. The Granth Sahib is not just a holy book of Sikhism but it is the eternal form of god which Sikhs worship. All the copies of the Adi Granth (first Punjabi book) are the same and called Saroop. The first word of the holy scripture is called Mool Mantra. The First line of the Sacred text is-"Ik Onkar sat-Nam Karata purakh nirabha'u niravair akal murat ajuni saibhan guru prasad" which means "There is one supreme being, the eternal reality, the creator, without fear and devoid of enmity, immortal, never incarnated, self-existent, known by grace through the True Guru."
