Prabhupada explains someone thinks he is free to smoke, free to drink alcohol; actually he exercises his freedom to become a slave to those habits. once he is surrendered to those habits he cannot stop. so he surrendered his freedom to serve those particular habits. where is the question of freedom? he has given up his freedom. the devotee does not remain subservient to any nonessential habit.
