Thus, it is not the temple that makes us Krishna conscious, rather it is what goes on inside the temple that does. There has to be bhagavat-katha. Prabhupada explained that he established these temples for people to come and hear about Krishna, because when one hears about Krishna, it awakens within the heart the desire to serve the Lord. When that desire is awakened, then it is natural inspiration. Devotional service has to be rendered in a voluntary spirit. That voluntary spirit or desire to do something to please the Lord has to be awakened from within the heart. That is the perfection of our service.
