Acharya Prashant explains that for Kabir Saheb, the term 'Shabd' does not refer to spoken words or mental thoughts, but to the 'Anhad Naad'—the unstruck, silent sound of the inner void. This sound is not a physical vibration caused by friction but represents a state of being where one lives in the truth. He clarifies that knowing the truth is synonymous with living in it; otherwise, there is no real knowing. This concept of the primordial vibration from which the manifest world arises is central to the teachings of both Kabir Saheb and Guru Nanak Dev Ji, where 'Shabd Kirtan' signifies tuning into this silent, joyful music of silence rather than mere vocal singing.
