This article examines the physics of cymatics — the geometric patterns sound produces in a resonating medium, first studied by Ernst Chladni in the 18th century and developed by Hans Jenny in the 20th — against the Nada Brahma ("sound is Brahman") tradition in Vedic philosophy and the acoustic engineering of temple Garbhagriha (sanctum) architecture. The article documents how ancient temple geometry, governed by Vastu Shastra principles, produces measurable standing-wave fields during mantra recitation, arguing that ancient sound science and modern wave physics describe the same phenomenon through independently developed frameworks.
