You should follow the example of Prahlada Maharaja. His father continually tortured him in so many ways, but he never protested against his father, but he never agreed with the opinion of his father. That should be your policy also, that you will never agree to your father's demoniac principles, but still you will try to serve him as faithfully as a nice obedient son. I am sure your father will be responsive and gradually our mission may be successful. I am always praying to Krishna to protect you because I know purposefully I have sent you in a fiery condition of maya.
Letter to Gargamuni, 22 November, 1968
