I. The Architecture of Sacred Motion
A Karana (करण) is the simultaneous combination of a Nritta-hasta (hand gesture in motion), an Angahara (body position), and a Chari (foot movement). This triple-simultaneity forces bilateral brain synchronization — engaging three distinct neural processing systems simultaneously. The Natya Shastra thus engineered a method for producing reliable, repeatable states of hemispheric coherence 2,000 years before neurofeedback technology confirmed its validity.
