'Religion is a doing and doing what is moral'. In Buddhism, particularly, there is such a great emphasis on moral doing that is very often designated as an 'ethical religion' (silaparaka dharma). The present work seeks to study Buddhist ethics as a development process not only in terms of inner dynamics of Buddhism inherent in its doctrinal and ethical formulations but also in terms of its response to various historical compulsions which motivated its followers to introduce in its general framework novelties of forms and expressions. It is hoped that such an approach would lead to a greater appreciation of Buddhist ethics both as an emergent of a unique spiritual vision and a social force. The book which is divided in six chapters cover the entire range of Buddhist development in India. The work is novel both in its approach and treatment of the subject. It studies conceptual formulations in their proper historical contexts. Modern debates on various ethical problems have been taken into account to bring about greater clarity in discussions.
