"The relationship between Gaudapada, Bhartrhari, and Shankara has never been given the in-depth exploration that Isayeva offers. Her analysis demonstrates a major continuity of thought from Gaudapada through Bhartrhari to Abhinavagupta and Kashmir Shaivism, a line hinted at by others but never analyzed in depth."Reading this book led to several 'aha' moments for me, as hunches I have had for many years were given detailed analysis and confirmation. But my eyes were opened as well to a new way of seeing the development of Indian philosophy during the crucial period of 500-1000 A.D. The author's bringing together of Gaudapada and Bhartrhari is a major step forward in scholarship." — H. G. Coward, University of Victoria
