Ek ong kaar, sat naam, karataa purakh, nirbho, nirvair
Akaal moorat, ajoonee, saibhang, gur prasaad. Jap!
Aad such, jugaad such, Hai bhee such, Naanak hosee bhee such.

One Creator. Truth is His name. Doer of everything. Fearless, Revengeless, Undying, Unborn, Self illumined, The Guru's gift, Meditate! True in the beginning. True through all the ages. True even now. Oh Nanak it is forever true.
The Mul Mantra translates as the root mantra from which a spiritual foundation is built. The Siri Guru Granth Sahib is based upon the concepts of the Mul Mantra.
Yogi Bhajan says on chanting the Mul Mantra
"The Mul Mantra is a fate killer. It removes the fate and changes the destiny to complete prosperity."
Osho translates the Mul Mantra as such
"He is one, He is Ongkar, the supreme truth. He is the creator, beyond fear, beyond rancor. He is the timeless form, never born, self- creating. He is attained by the guru's grace. He was truth before the ages and as time ran its course. Nanak says now is he truth eternal and forever will he be."
