Almost every follower of Srila Prabhupada accepts his statements as infallible like Vedic injunctions. However, we find grammatical and sometimes, even factual errors in his presentations (e.g. in a lecture, he says that Maharaj Dasaratha had two wives). Indeed there are plenty of errors in the original manuscripts of his books. Many of his conclusions on specialized fields are not in line with those of the experts. Since we accept him as a perfect authority on pure devotional service as well as on other ordinary subjects (like cooking, health, Sanskrit, psychology, anatomy, politics, economics, etc.), how can we resolve this apparent contradiction?
