Srila Bhaktisiddhanta Sarasvati Thakura remarks that people who are under the bodily conception of life are called materialists. If we accept the offerings of such people, place them before the Lord and invite Vaisnavas to partake of the prasada, that attempt will gain us only a material reputation, not the actual benefit of service to a pure Vaisnava. One should therefore try to serve the Supreme Personality of Godhead by fully surrendering at His lotus feet. If one engages for the service of the Lord whatever money one has honestly earned, that is spiritual service to the Supreme Personality of Godhead, the spiritual master and the Vaisnavas.
