The final conclusions of the Mundaka Upaniṣad (#19)

The knowledge of the Muṇḍaka Upanisad was spoken by Angirasa to Śaunaka Rsi long ago, but this knowledge remains up-to-date and relevant, just as other vedic texts. It teaches supreme knowledge, brahma-vidya, which can lead us to perfection. This knowledge should be taught only to qualified students who have abandoned the path of fruitive activities and are now aiming for spiritual realization in devotional service. After being reinstated in his original Krsna Consciousness, the soul shines in his original spiritual qualities.
