Now please continue to strictly follow the regulative principles and rigidly observing the four principal restrictions, namely: no eating of meat, fish or eggs, no taking of any kinds of intoxicants including coffee, tea and tobacco, no illicit sex life, and no gambling, and always without fail chant 16 rounds of the Holy Names daily, and be happy.
If you stick to these principles with determination, then you will become free from all attachment to maya, by Krishna's Grace.
Letter to daughter Haripuja, 25 June, 1972
