Almost. It's "what is" versus "what people imagine."
Imagine if I told someone making a sacrifice to Neptune/Poseidon before going on an ocean voyage were a complete waste, and the priesthood was knowingly or unknowingly suckering the people there to give offerings, but I was told in response it was necessary to ensure a safe voyage anyway. Tradition and the teachings of past generations become a burden and an impediment to progress if they are not periodically reexamined for validity.
