The book is also an introduction to the main topics of Hindu legal theory. Underlying the work of authors of various texts of Sanskrit juridicalliterature, including the dharmashastra, commentaries, and nibandhs, as well as of interpreters of questions concerning dharma, is a theory of the sources of dharma. Understanding the theory requires in-depth examination of the basis of the authority of different sources and of the issues that arisein case of conflict. The book begins with a detailed analysis the concept of dharma itself and the general problems concerning the knowledge of dharma (chapters 1-2). Then it studies the arguments used in the literature to establish the authority of sources (chapters 3-5). It pays special attentionto the authority of smrti and sadacara, which are the two crucial sources in the practical functioning of the system.

It concludes with a look at wider issues of legal theory, the acceptance of universal and particular authorities in Hindu jurisprudence, the role of rulers, and the law in practice.
