These mystic or heavenly inner Sounds are always resounding in the soul, thus when one attains a certain level of stillness and concentration, spiritual Sound becomes audible. In truth, the inner Sound is always there, it is we (our attention) who come and go. We gain awareness of the Sound, and this creates the illusion that the Sound has "arrived." When we get distracted or leave off our meditation practice it seems to us that the Sound has "stopped." However, this otherworldly Sound continues, like radio waves flowing through the atmosphere, available to be "tuned in" anytime we wish to listen (do bhajan: listen to the inner Sound in meditation).
