"People are invited to come to the temple to see the behavior of the devotees specifically in the matter of purification. There are two kinds of purification methods, external and internal. In our Krishna Consciousness Movement, Deity worship helps to keep us externally purified and Sankirtana helps to keep us internally purified.
"So as far as possible we shall execute both of these processes simultaneously. And by your exemplary character, the general mass of people will be benefited. Our hearts in material condition are filled with all dirty things, and this Krishna Consciousness Movement is the cleansing process."
(Srila Prabhupada lecture, December 15, 1969)
