But I think that the tuning forks are a modern method of the Buddhist practice of the bowls used in meditation practice that line up with different physiological and psychological regions of the body and mind. I am not knowledgeable enough on the topic to know if there are any therapeutic benefits. This might be difficult to determine if any beneficial therapeutic improvements are achieved via the sound or if the improvements are purely placebo.
