The ''Mul Mantar'' (, , pronounced Mool Mantar) is the first composition in the Sikh holy text and Great Living Guru, the Guru Granth Sahib, written in Punjabi. It is a series of affirmations and is the basis of Sikh theology, as well as the fundamental prayer. The Mul Mantar is the first composition of Guru Nanak Dev Ji. The Guru Granth Sahib begins with the Mul Mantar and it occurs more than one hundred times throughout the text where it is placed at the beginning of the particular Shabad. Bhai Mani Singh explains that the reason for placing the Mul Mantar at the beginning of a Shabad is that a Gursikh (Guru's Sikh) should remember that everything else will eventually be annihilated and only the Satnam (All-pervading Supreme Reality) will remain. It can be considered as the moral or the sole truth of the universe. The Mul Mantar is the most widely known part of Sikh scripture but it has posed a challenge to translators.
