“Become This Whole World”: The Phenomenology of Metaphysical Religion in Chāndogya Upaniṣad 6–8

Implicit in Heidegger’s 1920–1921 Phenomenology of Religious Life is an account of religion as a radical transformation of the very structures of experience. This article seeks to apply that account to a classical Indian discourse on reality and the self, Chāndogya Upaniṣad chapter six. This classical source-text for two thousand years of Hindu theology advocates a new ‘religious life’ achieved through phenomenologically reorienting the very structures of cognition toward the broadest truths of reality, rather than the finite features of the world. The goal is to create a new form of primordial subjectivity with an altered relationship to phenomena, finitude, and the divine. The article proceeds in two parts: The first section brings out Heidegger’s theory of religion through a reading of Heidegger’s 1920 Phenomenology of Religious Life with the help of his lectures, On the Definition of Philosophy, from the previous year. The second section tries to demonstrate the value of integrating traditional textual/historical scholarship in the Chāndogya Upaniṣad with Heidegger’s method. The juxtaposition aims to both (1) foreground the phenomenologically transformative goals of this influential Indian text, and (2) challenge Heidegger’s scepticism about the religious value of metaphysical reflection.
