This Upaniṣad ends on an auspicious note by prescribing a sādhanā, an aid to help overcome the obstacles in the way of this knowledge. The sādhanā prescribed is in the form of a very powerful prayer called Sri Rudram, which when chanted regularly reveals the truth of oneself as that which alone is -Kaivalyam.
