f you are no stranger to yoga classes, chances are one of your sessions may have ended with your instructor sealing the practice with healing sounds of gongs or chanting; a short and sweet immersion into a sound bath. This is just a small sampling of the power of auditory therapy, which can offer tones and music as a means of healing and relaxation, a practice that dates back through different cultures and time periods, from Tibetan singing bowls to Greek sound vibrations and Aboriginal didgeridoos. Increasingly these days, therapists and wellness practitioners are harnessing the purification and benefits of this concept in full on sound bath meditation seminars, some of which can last up to hours on end.
