Rasa is a concept from Indian aesthetics that refers to the emotional flavor or essence experienced by an audience when engaging with art, literature, or performance. It encompasses a range of feelings, such as joy, sorrow, or love, and is essential in creating a connection between the work and its audience. In traditional Indian drama and dance, rasa is often categorized into nine primary emotions, known as the navarasa. These emotions help artists evoke specific feelings, allowing the audience to experience a deeper understanding and appreciation of the performance.
