The medieval period of Japanese religious history is commonly known as one in which there was a radical transformation of the religious culture. This book suggests an alternate approach to understanding the dynamics of that transformation. One main topic of analysis focuses on what Buddhism - its practices and doctrines, its traditions and institutions - meant for medieval Japanese peoples themselves. This is achieved by using the notions of discourse and ideology and juxtaposing various topics on shared linguistic practices and discursive worlds of medieval Japanese Buddhism.
