Concept:
The Natyashastra written by Bharata Muni is the foundational treatise on Indian classical dance, drama, and music. It contains detailed explanations of dance movements, expressions, gestures, dramatic presentation, and performance techniques. The text dedicates an entire chapter called Tandava Lakshanam to explain the concept and characteristics of Tandava dance.
