The book begins with a comparative typology of traditional classical epics, arguing that epic is a distinctive mythical genre, and that the Mahrib/grata in particular should be studied as part of an Indo-European epic (and not just mythical) continuum. The reshaping of Indo-European themes is then examined in relation to the Mahabharata's central mystery: the figure of Krishna, hero and ally of the Pandava brothers in their struggles against their cousins, the Kauravas, and incarnation of Visnu.
The study argues that Krishna figures in the epic at the center of a coherent theological ensemble that builds upon continuities in Indo-European, Vedic and particularly Brahmanic sacrificial idioms. Ultimately, Krishna guides the forces of dharma or righteousness through a great "sacrifice of battle" whose eschatological background recalls Indo-European and Vedic themes, while projecting them into the Hindu bhakti cosmology of universal dissolution, recreations and divine grace. The study vigorously opposes attempts to "explain" Krishna by arbitrary theories of the Maluibhdrata's growth through interpolations.
