Adi Shankara

788

Shankara composed commentaries on ten principal Upanishads — the ancient forest texts that conclude the Vedic corpus and provide the foundational source material for all Vedantic philosophy. His Bhashyas on the Brihadaranyaka, Chandogya, Taittiriya, Aitareya, Kena, Katha, Isha, Mundaka, Mandukya, and Prasna Upanishads constitute a unified interpretive achievement: read together, they demonstrate that the Upanishads consistently teach the non-dual identity of atman and Brahman, dissolving all apparent differences between the individual self and the absolute ground of being. Each commentary is simultaneously a work of textual exegesis and a work of philosophical argument, engaging with rival interpretations and showing — often through subtle analysis of a single word or particle — that the Upanishadic sages spoke with one voice. These commentaries remain the primary text-critical resource for Advaita Vedanta and the benchmark against which all subsequent Upanishadic scholarship has been measured.
