The marketplace of the holy name is the place where the pure holy name is distributed. This pure holy name cleanses the heart of all the anarthas. If a devotee wants to be successful in giving shelter to others, he has to be an ideal example in a way that he is visibly chanting Hare Krishna. Others should see how he is chanting Hare Krishna; how he is chanting Hare Krishna with others; and how chanting Hare Krishna is the foundation of his spiritual life. When he is not chanting japa, he is chanting in kirtana.
