Sound has always been medicine. Long before we had the language of neuroscience, the world's contemplative traditions understood that the right vibration could reorganize a body.
We now know that low-frequency tones stimulate the vagus nerve, that rhythmic auditory input entrains brainwave patterns, and that group resonance produces measurable shifts in cortisol and heart-rate variability. None of this is mystical. It is the same body it was a thousand years ago.
What the lab confirms, the cushion has always known.
