In the present work which is a critique of Vedanta the author has applied Dr. A.N. Whitehead's approach to philosophy and in particular his definition of an entity which entails a process metaphysics. Having deeply studied the ultimate metaphysical positions of the Vedantic School of thought, he has subjected the three well-known systems of Advaita, Visistadvaita and Dvaita to a critical analysis in the light of rational metaphysics based on an adequate analysis of our common and immediate experience in its widest scope. This book is an original attempt which is bound to stimulate new thinking among protagonists of India's Vedanta philosophy. This work is an unprecedented critical exposition of the logical structure of three main Vedantic schools and merits consideration by all lovers of truth in philosophy.
