This work investigates how the fifth-century commentator Buddhaghosa conceptualized the nature, authority, and ethical implications of the Buddha's speech. Maria Heim, a scholar of South Asian religions, examines Buddhaghosa's extensive commentaries to reconstruct a sophisticated theory of language that bridges the gap between human communication and the transcendent truth of the dharma. The text argues that for Buddhaghosa, the Buddha's words function as a precise instrument for moral transformation rather than merely a repository of propositional facts.

Scholars in the field of Buddhist studies recognize this text as a significant contribution to the understanding of classical Indian hermeneutics. Readers frequently note the academic density of the prose, which requires a foundational knowledge of Buddhist terminology to fully grasp the author's arguments.
