Abhinavabharati is a Sanskrit commentary on the Natyasastra, an ancient treatise on dramatic theory by Bharata Muni.
The Abhinavabharati was written by Abhinavagupta (c. 950–1020), the great Kashmiri Saivite spiritual leader and a yogi.
In this monumental work, Abhinavagupta explains the rasasutra of Bharata in consonance with the theory of abhivyakti (expression) propounded in Anandavardhana's (820–890) work Dhvanyaloka ("aesthetic suggestion"), as well as the tenets of the Pratyabhijna philosophy of Kashmir.
Abhinavagupta maintains that this rasa (literally, taste or essence, the outcome)[1] is the summum bonum of all literature.
