This book is an enquiry into the concept of the 'self', transcending the barriers of 'non-self' and realizing the non-dual Consciousness within and without. This concept is the central theme of Advaita Vedanta. The Drg-drsya-viveka is a short treatise of forty-six Sanskrit verses which analyses the illusory perceptions of names and forms in the states of dreams and waking as well. The commentator gives a scientific explanation of the meaning of Self and Non Self, helping the reader to discriminate and separate the observer (drk) from the observed objects (drsya).
