Meaning is a lower-order form than a yajna. "Meaning" is a transcription into text, into some other words. This arises from Christian idea that any ritual must be rooted in belief/doctrine.
Let rituals be meaningless.
It is similar to sticking one's nose in gadget without looking at reality around and being unable to experience it.
"Superstition" is a word from Christian theology, it has no other "meaning."
