If your father fortunate, and I think he is fortunate, because he has got two nice sons, so Krishna is certainly pleased on him. His present demoniac qualification is no bar for getting mercy of Krishna, because you are two sons present for his salvation. Just like Prahlada Maharaja—his father was atheist, and he was always inimical to his great son, but still the son was so good that he arranged for the salvation of his father. So Vaisnava son in a family can give the best service to his family members, and you are ideal two brothers in this country, and you show the example how everything can be adopted, in the service of Krishna.
Letter to Brahmananda, 16 October, 1968
