"By the grace of the Lord, if a devotee, at the time of death, can simply chant His holy name -- Hare Krsna Hare Krsna Krsna Krsna Hare Hare/ Hare Rama Hare Rama Rama Rama Hare Hare -- simply by chanting this maha-mantra, he immediately surpasses the great ocean of the material sky and enters the spiritual sky. He never has to come back for repetition of birth and death."
(Srimad-Bhagavatam, 4.10.30, Purport)
