Srila Prabhupada chants the Hare Krishna mantra:
"Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare,
Hare Rama, Hare Rama, Rama Rama, Hare Hare."
"The transcendental vibration from the mouth of a pure devotee is so powerful that it can revive the living entity's memory of his eternal relationship with the Supreme Personality of Godhead. In our material existence, under the influence of illusory maya, we have almost forgotten our eternal relationship with the Lord, exactly like a man sleeping very deeply who forgets his duties. In the Vedas it is said that every one of us is sleeping under the influence of maya. We must get up from this slumber and engage in the right service, for thus we can properly utilize the facility of this human form of life. As expressed in a song by Thakura Bhaktivinoda, Lord Caitanya says, jiva jaga, jiva jaga. The Lord asks every sleeping living entity to get up and engage in devotional service so that his mission in this human form of life may be fulfilled. This awakening voice comes through the mouth of a pure devotee."
(Srimad-Bhagavatam 4.20.25, Purport)
All glories to Srila Prabhupada.
