Classical Indian Drama is a rich tradition of Theatrical Performance that dates back to Ancient India, primarily characterized by its Integration of music, dance, and dialogue, as seen in works like Kalidasa's 'Shakuntala'. It is deeply rooted in the Natyashastra, an Ancient Sanskrit treatise on Performing Arts, which outlines the Principles of drama, including the use of 'rasa' or Emotional flavors to engage the audience.
