Nathmal Tatia, one of the leading Jaina scholars of our time, provides us with the first systematic and in-depth study of the great problems dealt with in Jaina philosophy. It begins with the basic Jaina worldview of non-absolutism (anekanta-vada), and deals next with Jaina epistemology. Three major topics are then studied in great detail, with full reference to the Jaina scriptures. These are: the problem of avidya in the various Indian schools; the Jaina doctrine of karman; and Jaina yoga. This latter includes an important study of Haribhadra"s comparative studies in yoga. Tatia has here given us a first-rate advanced level study of Jaina philosophy.
