ei nimantraṇe dekhi, — ‘pratiṣṭhā’-mātra phala
“ ‘My consciousness is impure because I accept all these goods from people who are interested only in pounds, shillings and pence. Therefore by this kind of invitation I get only some material reputation.
Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura 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 Vaiṣṇavas to partake of the prasādam, that attempt will gain us only a material reputation, not the actual benefit of service to a pure Vaiṣṇava. 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 Vaiṣṇavas.
