In the Hare Krsna movement, the chanting of the Hare Krsna maha-mantra, the dancing in ecstasy and the eating of the remnants of food offered to the Lord are very, very important. One may be illiterate or incapable of understanding the philosophy, but if he partakes of these three items, he will certainly be liberated without delay.
From Srila Prabhupada's purport to Cc Madhya 15.237
