From the time of the Mauryas Jainism was an important factor in the religious life of the area formerly known as Mysore (now Karnataka). The Jains were pioneers in the development of the kannada language, and they contributed greatly to many aspects of the cultural life of the region. This work is the result of the research (for Ph.D thesis of the author) into the religious history of the Jainas in Karnataka who dominated the political and cultural life of Karnataka for about one thousand years during the early medieval period. Based on an analytical study of literary and epigraphic sources, it attempts to explain the prevalence of image worship, tantrism, priesthood and ritualistic formation which characterized Karnataka Jainism in the early medieval period. The book also seeks to examine the social and economic basis of Jaina monasteries in all parts of the Kannada region.
