1. Use your American and European brains to increase

    I especially want that my books and literatures should be distributed profusely, but so far I understand this is not being done very perfectly. So I want that you all my students shall very vigorously try for this book distribution. Do not hesitate to use your American and European brains to increase, that is Krishna’s special gift to you, now use it. Any activity which will please Krishna should be accepted favorably, this is our guiding principle. Now apply it in this way, by doing everything and anything for spreading this Krishna Conscious literature, and this is really pleasing to Krishna, know it for certain.
