ANHAD/ANHAT BANI or SHABD
ANHAD/ANHAT BANI or SHABD :A sound that is unending and knows no limits. Audible life current originating from the Divine Will, endlessly carrying on the work of creating and sustaining the universe; interchangeably used with Anhat meaning \’Unstruck\’, as it it automatic and not instrumental. It also means sound not produced by physical concussion; the mystic melody or music believed to be heard by the Yogis (persons of high spiritual attainment) in a state of ecstasy or super conciousness.
In Gurbani it is used as a symbolical expression for experience of higher truths or inner music which gives a feeling of divine bliss. This is due primarily to Nam Simran (meditation) blessed by the grace of the Guru. Guru Nanak says. “By following the steps or the Guru, practising his way of life, the flow of soundless music is felt within”. (Adi Granth, p. 922)
