A sannyasi is supposed to beg from door to door. He does not beg simply because he is hungry. His real purpose is to enlighten the occupant of every house by preaching Krsna consciousness. A sannyasi does not abandon his superior position and become a beggar just for the sake of begging. Similarly, a person in householder life may be very important, but he may also voluntarily take to the mendicant way of life. Rupa Gosvami and Sanatana Gosvami were ministers, but they voluntarily accepted the mendicant's life in order to humbly preach Sri Caitanya Mahaprabhu's message. It is said about them: tyaktva turnam asesa-mandala-pati-srenim sada tuccha-vat bhutva dina-ganesakau karunaya kaupina-kanthasritau. Although the Gosvamis were very aristocratic, they became mendicants just to deliver the fallen souls according to the order of Sri Caitanya Mahaprabhu. One should also consider that those who engage in the missionary activities of Krsna consciousness are under the guidance of Sri Caitanya Mahaprabhu. They are not actually beggars; their real business is to deliver fallen souls. Therefore they may go from door to door just to introduce a book about Krsna consciousness so that people can become enlightened by reading. Formerly brahmacaris and sannyasis used to beg from door to door. At the present moment, especially in the Western countries, a person may be handed over to the police if he begs from door to door. In Western countries, begging is considered criminal. Members of the Krsna consciousness movement have no business begging. Instead, they work very hard to introduce some books about Krsna consciousness so that people can read them and be benefited. But if one gives some contribution to a Krsna conscious man, he never refuses it.
