Brahman in Ramanuja's philosophy is not a non-relational and non-differentiated bare being, but a living reality, a relational whole, who is inseparably related with the order of individual self cit and of matter acit. Thus the relation of inseparability aprthak-siddhi-bhava is fundamental to Ramanujas metaphysics. It is the central concept around which Ramanuja's whole philosophy revolves. Thus it is both possible and fruitful to view Ramanuja's metaphysics through the perspective of this unique relation of inseparability. In this book such an attempt is critically carried out.
