In this lecture, we peel back the layers of this 5th-century CE mystery. We explore a text so compressed that a three-word sentence can unlock the secrets of the universe—or remain completely incomprehensible. Join us as we investigate the man (or the myth) who turned the ancient Upaniṣads into a rigorous system of logic, challenged the power of Vedic rituals, and left a philosophical puzzle that scholars are still trying to solve today.
