The book deals with the iconography of Sadasiva, an important form of Lord Siva. It has four chapters: Sadasiva, Mahasadasiva, the Consort of Sadasiva, and Resume. The Sadasiva aspect of Siva, having five heads and ten arms, did not receive much attention from the scholars so far. The present book envisages to bring together all the material bearing on the subject. A number of photographs, mostly of unpublished sculptures, bronzes and miniature paintings representing different phases of Indian art, illustrate the text and make the book useful for the students of art, iconography, religion and philosophy. The seven appendices, appended at the end, provide information as gleaned from religious and secular literature related to the subject.
