1. Principles of religion are not dogmas and formulas

    Behavior (following regulative principles) not theoretical knowledge — is paramount for the aspiring spiritualist:

    The principles of religion, namely austerity, cleanliness, mercy and truthfulness… may be followed by the follower of any faith. … 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.
