The Natya Shastra (literally, "the treatise on drama and dance") is one of the most comprehensive and ancient texts on performing arts ever written. Composed by the sage Bharata Muni somewhere between 200 BCE and 200 CE — scholars debate the exact date — it runs to thirty-six chapters and covers everything from stage architecture and casting to the physiology of emotional expression. It is the foundational grammar for virtually every form of classical Indian dance, music, and theatre that exists today.
The Theory of Rasa
The most influential concept in the Natya Shastra is the rasa theory. Bharata Muni identifies eight rasas — the aesthetic emotions that a performance aims to evoke in the audience: shringara (love), hasya (humour), karuna (pathos), raudra (fury), vira (heroism), bhayanaka (terror), bibhatsa (disgust), and adbhuta (wonder). A ninth rasa — shanta (tranquillity) — was added by later commentators. The rasa theory argues that the purpose of art is not merely to represent reality but to distil it into pure aesthetic experience — a state of rasanubhava (tasting the essence) that the audience shares with the performer.
Abhinaya: The Four Channels of Expression
The Natya Shastra codifies abhinaya — the art of expression — into four channels. Angika abhinaya is expression through the body: the 108 karanas (combined positions of the body and feet), mudras (hand gestures), and eye movements. Vachika abhinaya is expression through speech and song. Aharya abhinaya is expression through costume, makeup, and ornaments. Sattvika abhinaya — the subtlest and most prized — is expression through involuntary emotional states: goosebumps, trembling, tears. Classical dancers spend lifetimes mastering these channels.
Tala and Laya: Time in Music and Dance
The Natya Shastra also provides detailed accounts of tala — the rhythmic cycle that organises time in music and dance. It describes the mathematical subdivisions of beats, the roles of different percussion instruments, and the relationship between the dancer's footwork and the percussionist's patterns. This system of tala has evolved over two millennia into the intricate Carnatic and Hindustani rhythmic frameworks used today — but the underlying principle, that time in performance is cyclical and countable, descends directly from Bharata Muni's treatise.
Legacy and Living Influence
The Natya Shastra is not merely a historical document. It is a living reference that practitioners, choreographers, and scholars consult actively. When a Bharatanatyam teacher corrects a student's aramandi (half-sitting stance), she is applying a physical specification that the Natya Shastra describes. When an Odissi dancer shapes a specific hasta mudra, she draws from a vocabulary that Bharata Muni catalogued. The text's influence is so pervasive that it has been called the "fifth Veda" — a testament to its cultural status as sacred knowledge, not merely academic theory.
