Aprakrta sound can be understood only by inspiration or initiation
There is a gulf of difference between the two qualities of sound, namely prakrita and aprakrita. The physicist can deal only with the prakrita sound, or sound vibrated in the material sky, and therefore we must know that the Vedic sounds recorded in symbolic expressions cannot be understood by anyone within the universe unless and until one is inspired by the vibration of supernatural (aprakrita) sound, which descends in the chain of disciplic succession from the Lord to Brahma, from Brahma to Narada, from Narada to Vyasa and so on. No mundane scholar can translate or reveal the true import of the Vedic mantras (hymns). They cannot be understood unless one is inspired or initiated by the authorized spiritual master.
