Book Distribution is our real business. If we give them a record, they simply hear some magical sounds and take it for sense gratification, but if they receive one of our books and read even one page, they get eternally benefited. – Letter to Ajita, 6 January, 1975
To associate with the holy name and chant the holy name is to associate with the Personality of Godhead directly.
Everything is done by the supervision of the Supreme Personality of Godhead.
Srimad Bhagavatam 3.31.1,
Srila Prabhupada
Everything can be used to the extent that it can be engaged in Krishna’s service.
