The earlier volume in this series dealt with two religions of Indian origin, namely, Buddhism and Jainism. The Indian religious scene, however, is characterized by not only religions which originated in India but also by religions which entered India from outside India and made their home here. Thus religious life in India has been enlivened throughout its history by the presence of religions of foreign origin on its soil almost from the very time they came into existence. This volume covers three such religions - 0Zoraoastrianism, Judaism, and Islam. Indeed, all three religions share the dual feature that they have profoundly influenced Indian religious life and have also in turn been profoundly influenced by their presence in India.
