Synopsis In this book only some portion of my PhD thesis is appearing in published form. In the first chapter I have traced the origin of dance from the Vedic period and its evolution and development latter Indian Classical Dance Style known as Bharata Natyam, here a good material is supplied regarding the position of Devadasis. In the second chapter the general idea is given about the subject of Natyashastra. In the third chapter however attention is concentrated on Rasadhyaya and Bhavadhyaya of Bharata's Natyashastra and Abhinaya, Dharmi, Vrtti Pravrtti, Tandava, Lasya, the types of hero and heroines and Tala and Sangita. The fourth chapter deals with the theory and technique of Angikabhinaya not only in Bharata's Natyashastra but also in other allied texts. Here also the charts are presented and photographs are added. So far as the second part of the work is concerned there is a discussion on contemporary Bharata Natyam, its innovations. For the benefit of students and their future guidance proper care is taken to give the explanation of technical terms of Bharata's Natyashastra with the help of other Ancient Sanskrit texts with notations and charts.
