These are the opening words of the Guru Granth Sahib, the holy scripture of the Sikhs, said to be the first words spoken by Guru Nanak upon his enlightenment. ‘Ek Omkar’ could be understood as the One True Sound.

Ek Omkar
     One God,
     One Song,
     One Creation–

The true name,
creator of the universe,
beyond fear and conflict,
omnipresent,
unborn, undying, self-existent,
grace of the guru.

Chant this again and again!
From the beginning, truth,
throughout the ages, truth,
in this moment, now, truth!
Says Nanak, ever true!
