What causes the living entity to turn to Krishna? The first cause is when he hears the message of Godhead from a devotee. This causes him to turn his attention to the Lord. A preacher understands that the message he is delivering is not his own, but the Lord’s. A devotee who preaches with this understanding invokes Krishna’s presence in his words. Krishna then helps the living entity hear His message. Again, it is important for a devotee preacher to set a good example so that not only can he invoke the Lord in his words but that the living entity has something to emulate.
