Srila Prabhupada: The general mass of people, although sudras and less, can be purified by chanting this Hare Krishna mantra. Then they can understand the exalted philosophical statements of Bhagavad-gita and Srimad Bhagavatam. Our Krishna consciousness movement has therefore adopted the chanting of the Hare Krishna maha-mantra for the general masses. (Srimad-Bhagavatam, 5.10.18 Purport)
