We shall only do one business and that is book-selling. That's all. As soon as you become karmis after business, then spiritual life becomes damaged. This business should not be encouraged any more. Doing business and not sankirtana, this is not at all good. Visaya chadiya kabe suddha ha'be mana/ kabe hama herabo sri-vrndavana. "When the mind is completely purified, being freed from material anxieties and desires, then I shall be able to understand Vrndavana and the conjugal love of Radha and Krsna, and then my spiritual life will be successful.'' One has to engage himself in devotional service, giving up the engagement of manufacturing pounds, shilling, pence.
