Sat Nam, sometimes written Satnam or Sat Naam, is the main mantra that appears in the Sikh sacred scripture called the Guru Granth Sahib. Sat Nam loosely translates as ‘the name that is true and everlasting’. Sat Nam is often repeated as a complete mantra, exclamation or part of a longer mantra by Kundalini yoga practitioners. In his teachings, Guru Nanak, the founder of Sikhism and the first of the ten Sikh gurus, emphasised the need for repeating Sat Nam to realise the all-pervading supreme reality in the universe. In many spiritual and contemplative traditions, Sat Nam refers to a higher being or God, supreme good, source or the Tao.
