This paper critically reads and analyzes the first discourse of Āruṇi and Śvetaketu in the first half of the sixth chapter of the Chāndogya Upaniṣad. It argues that, except for a few interpolated lines in VI.2 and VI.3, the entire discourse constitutes one integrated whole with a specific indicatory knowledge at its core that indicates deeper truth underlying all realities, and its characterization and twofold elaboration with reference to macro- and microcosmos. In light of two cosmogonic accounts from the JaiminīyaBrāhmaṇa (...) and some other Vedic passages, this paper argues that Āruṇi’s cosmogony originally posited asat as the primordial entity, which has not yet acquired any phenomenal form. Incidentally it also demonstrates that in this discourse the term ādeśa cannot denote a ‘method of substitution’ as proposed by Thieme and taken over since then by several scholars. (shrink)
