In the purport to Srimad Bhagavatam First Canto, Chapter Seventeen verse Thirty-two, — BEFORE 3.25.21) Srila Prabhupada writes: The principles of religion, namely austerity, cleanliness, mercy and truthfulness, as we have already discussed, may be followed by the follower of any faith. There is no need to turn from Hindu to Mohammedan to Christian or some other faith and thus become a renegade and not follow the principles of religion. The Bhagavatam religion urges following the principles of religion. The principles of religion are not the dogmas or regulative principles of a certain faith. Such regulative principles may be different in terms of the time and place concerned. One has to see whether the aims of religion have been achieved. Sticking to the dogmas and formulas without attaining the real principles is not good.
