Bringing prior instructions given by Prabhupada to contradict a later direct order – such as the letter of July 9, 1977 , the formal directive designating ritvik representatives – is crazy.
SRILA PRABHUPADA: “I may say many things to you, but when I say something directly, “Do it”, your first duty is to do that. You cannot argue, “Sir, you said me like this before.” No, that is not your duty. What I say now, you do it. That is obedience. If the captain of the ship says “Five degrees starboard” and the first mate replies, “But captain, before you told me ‘Ten degrees port’,” then it can be understood that the first mate has gone insane.” — lecture by Srila Prabhupada on the Srimad-Bhagavatam, Hyderabad, India, April 15, 1975
