Eastern mystics tend to identify sound as the primal energy of life. Sound is considered to be the original life force out of which all else unfolds. Hence the Christian and Jewish idea: in the beginning was the Word (dabhar), the energy of sound. Many Eastern meditation techniques use mantras, not for their theological or religious meaning, but for the sound quality of the words. They believe that the regular use of the mantra realigns the meditator with the original creative energy, not merely of one's own life, but of cosmic life in its totality.
