Srila Prabhupada has explained that in all temples both pancaratrika vidhi and bhagavat vidhi must go on side by side. When there is both preaching and Deity worship going on, then the temple is well-balanced. Without preaching, and especially book distribution, there is no meaning to temple life. You should not be proud of the fact that you are distributing books. Better to be a sincere potwasher, always meditating on service to the lotus feet of the Deity, then to be a proud book distributor, always meditating on one's own honor. But the fact is that when the book distribution is going on in a sincere way, the whole community benefits.
