Kali-Saṇṭāraṇa Upaniṣad

The text asserts that the audible chanting of this mantra is a means to wash away all the tribulations of the current era (Kali Yuga).

[9] Popular in Gaudiya Vaishnavism denomination of Hinduism, its devotees assert that the effect of reciting this mantra in Kali-Santaraṇa text is to imbue the pleasure principle emanating from the very innermost part of one's being, feel transcendental ecstasy and revive deep consciousness, remembering the love of God, and to getting rid of the harmful influence of the Kali Yuga.

However, Narada who is the arbitrator of the laws of karma (all deeds) himself approaches Brahma seeking redress to all the ills of this epoch.

It is also stated in the Upanishad that Narada roamed around the world holding a lute in his hand to adjust the laws of harmony as a result of a curse by Daksha.

[16] From 16th-century onwards, in Gaudiya Vaishnavism, great importance has been given to public, vocal audible chanting or singing of the maha-mantra with the divine names of Hindu gods Krishna, Rama and goddess Radha (Hare).

This at least is the interpretation given in Rupa Goswami's Prathama Chaitanyaashtaka which states that Chaitanya himself had chanted this maha-mantra in a loud voice.

[18] The Maha-mantra of the Upanishad is part of the Gaudiya tradition legends, and the chant that was used to deconvert Muslims and initiate them to Vaishnavism in Bengal.

[19] In the biographies of Chaitanya Mahaprabhu, a Bhakti movement saint poet, the mantra he received when he was given diksha or initiation in Gaya was the maha-mantra of the Kali-Santarana Upanishad.

[24] Titled "Hare Krishna Mantra", the song reached the top twenty on the UK music charts, and was also successful in West Germany and Czechoslovakia.
