Mundaka Upaniṣad: Śaunaka's Question to Angiras

The Mundaka Upaniṣad, a significant text within Vedic literature, details profound philosophical inquiries. In this Upanishad, a specific dialogue unfolds where a seeker approaches the revered sage Angiras.

The seeker's primary goal was to gain knowledge about the fundamental principle through which everything else could be understood. The exact question posed was: 'What is that by the knowing of which all this becomes known?'

According to the scriptural account in the Mundaka Upaniṣad, it was Śaunaka, a prominent householder and follower of Shaunaka Rishi, who approached Sage Angiras with this profound query.

The question seeks the knowledge of the ultimate reality or the supreme cause, understanding which, as the question implies, leads to the comprehension of the entire universe and existence.

Therefore, among the given options:

• Uddālaka
• Śaunaka
• Śvetketu
• Janaka

Śaunaka is identified as the individual who approached Angiras with this fundamental question about knowledge.
