Happy Gopastami celebration in Vrindavan (Album of photos)
Srila Prabhupada: The general mass of people, although sudras and less, can be purified by chanting this Hare Krishna mantra.

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)
