As long as we keep ourselves pure for preaching, then we shall have all good results - of that there is no doubt. One thing, make certain that your routine work is going on nicely - chanting 16 rounds, rising early, cleansing, street Sankirtana, etc. - then all other programs will be successful. If routine work becomes slack or neglected, then all other attempts will fail.
Letter to Cyavana, 26 December, 1971
