Ik ( ਇੱਕ) is interpreted as 'one and only one, who cannot be compared or contrasted with any other', the 'unmanifest, Lord in power, the holy word, the primal manifestation of the Godhead by which and in which all live, move and have their being and by which all find a way back to Absolute God, the Supreme Reality.' The first symbol 'ik' is actually not a word but the Punjabi symbol for the number 1. Ik Onkar are the first words of the Mul Mantar and also the opening words of the Sikh holy scripture Guru Granth Sahib.
It is a central tenet of Sikh religious philosophy. Ik Onkar, also spelled Ek Onkar or Ik Oankaar ( Gurmukhi: ੴ or ਇੱਕ ਓਅੰਕਾਰ Punjabi pronunciation: ) literally, 'one Om', hence interpreted as 'There is only one God or one Creator' ) is a phrase in Sikhism that denotes the one supreme reality.
