According to Advaita-Vedanta, God or Brahman is identical with the inner self (the Atman) of each person, while the rest of the world is nothing but objective illusion (maya).
This book clarifies the relationship between God and the creation for Gaudapada, Bhartrhari, and Shankara, and by doing so, demonstrates a major continuity of thought from Gaudapada through Bhartrhari to Abhinavagupta and Kashmir Shaivism.
