What do you mean by superstitious worship of big stones?

Hehe, is there anything in the big stone? If it's just a stone, is there any merit? What does an inanimate object do when it worships?

This is really superstitious. Buddhism generally worships the opposite situation with merit and kindness. It is inevitable that parents are a boon field and the three treasures of Buddha are a merit field. Worship your parents because you are grateful for their upbringing, and worship Buddha because you can get great blessings and great merits.

Where are the stones? What is its purpose? There's no way to talk about it. It's pure superstition!
