The self-contradictions of the Mayavadis

Although the impersonalist rises to the Brahman effulgence and enters into that effulgence, he has no engagement in the service of the Lord, and therefore he is again attracted to materialistic philanthropic activities. Thus he comes down to open hospitals and educational institutions, feed poor men and perform similar materialistic activities, which the impersonalist thinks are more precious than serving the Supreme Personality of Godhead. Anadrta-yusmad-anghrayah. The impersonalists do not think that the service of the Lord is more valuable than serving the poor man or starting a school or hospital. Although they say brahma satyam jagan mithya–“Brahman is real, and the material world is false”–they are nonetheless very eager to serve the false material world and neglect the service of the lotus feet of the Supreme Personality of Godhead.
