Acharya Prashant explains that while teaching styles may vary among teachers, the core truth must remain consistent, much like the principles of science. He suggests that selecting a spiritual teacher should not be a matter of blind faith but should involve rational criteria. One can easily filter out ninety-nine percent of self-proclaimed religious leaders by rejecting those who promote superstition, support outdated social dogmas like the caste system, or hold regressive views about women. He emphasizes that any teacher who speaks against scientific facts or makes false claims about supernatural powers should be barred from educational institutions, as science can easily debunk such falsehoods through experimentation.
