One thing is clear that fighting with other human beings in the name of religion is subhuman. As a religious man, we are fellow-travellers in the direction of the realm of spirit. Here the nomenclature of Hindus, Muslims, Christians, etc., ceases to be meaningful. Of course, we have to go very far and we have not made any beginning yet. However, at present the advaitic principle of difference less Brahman can serve the purpose of harmonizing all religions. Here we have adopted this principle. Secondly, the key-concepts of different religions have been shown to mingle into one another. The book attempts to interrogate the categories used in western discourse in the study of religion. In doing so, the book outlines a broad overview of the discussions on issues relating to the methods and theories in the study of religion. The book provides an insight into some of the key issues that need clarity in dealing with religions. This scholarly presentation is a must read for students of religion, culture and philosophy and for those involved with the struggles of the subaltern community.
