This book deals with the Vedanta standpoint, according to which there are six sources of knowledge. The conceptions of these different kinds of knowledge, with all the arguments given by the Vedantins to prove their independence and ultimacy, are critically discussed here in the light of modern Western concepts and the attempt has been made to present the conclusions to students of Western Philosophy in a clear and lucid form. As the purpose of this work is to bring the problems, concepts and theories of the Vedantins within the focus of modern Western thought, the method adopted is one of critical analysis, comparison issues from extraneous aspects with which they are often associated.
