Sound bath

The name describes the arrangement rather than any claim: you lie down, usually with a blanket and a bolster under the knees, and the sound surrounds you. There is no melody to follow and nothing to do. A practitioner moves between hammered metal bowls, crystal bowls, a gong and small cymbals, building layers and then thinning them out again. A full session runs about sixty minutes.

What it is for is deep rest. With no rhythm to predict, the part of attention that forecasts has nothing to do and quietens; with the eyes covered and the body still, breathing slows and the exhale lengthens, which shifts the nervous system towards its resting branch. Common reports are heaviness, tingling hands, losing track of time and small involuntary twitches. The research base is small and mostly self-reported — enough to support short-term drops in tension and better sleep that night, not enough to support any treatment claim.

In a KEO session, a full sound bath is its own format, held in Bangkok and in Phichit, with mats, blankets and eye covers provided. It is the easiest class to attend first because there is no posture to learn. Tell Ben beforehand if you have a pacemaker, a recent injury, are in the first trimester of pregnancy or have a history of seizures: bowls then stay off the body and you lie further from the gong.
