Acharya Prashant clarifies the meaning of 'Anhad', a term used by Guru Nanak and other saints, explaining that it is not a physical sound or an aural sensation. He emphasizes that hearing the Anhad is synonymous with touching nothing, thinking nothing, and being nothing. It represents the purest state of being, which is formless, soundless, and thoughtless. The sense of hearing is merely used as a metaphor for a much larger spiritual principle of non-duality and the absence of the ego. To hear Anhad is to be 'nowhere' and to be a 'nobody', transcending all identities and attachments. The speaker criticizes common misconceptions and fraudulent interpretations of Anhad, such as associating it with insect sounds, ultrasonic vibrations, or cosmic rays from distant galaxies. He asserts that spirituality is not foolishness and requires a sharp intellect to transcend the intellect itself. Anhad is described as the 'soundless sound' and the 'great-grandfather of all Koans', surpassing the Zen concept of 'one hand clapping' by pointing toward 'no hand clapping'. Ultimately, Anhad signifies residing in a state of non-duality, free from the traps of concepts and the conflicts inherent in duality.
