The study and practice of 'Nava Rasa' ('Nava' means nine and 'Rasa' means sentiments) is an important aspect of learning Abhinaya in Bharatanatyam. According to Indian aesthetics, 'Rasa' is the taste or the flavour of an art, object or work. The 'Nava Rasas' are universally felt and experienced by everyone alike. 'Rasa' has no exact meaning; it can be described, however, as an aesthetic experience felt by the spectator, which results from the artist's soulful performance filled with 'Bhava'. 'Bhava' is the emotional feeling or (an) expression felt and expressed by the performer. It is an existing condition of the artist. According to Natyashastra, there are eight 'Rasas.' The text 'Abhinaya Darpana' by Nandikeshwara includes peace ('Shantham') as the ninth 'Rasa'. The 'Nava Rasas' are: Love (Sringaram), Courage (Veeram), Pathos (Karunyam), Wonder (Adhbhutam), Mirth (Hasyam), Fear (Bhayam), Disgust (Bheebhatsam), Anger (Roudram), and Peace (Shantham).
