What zodiac is the clay idol?

Do you mean "clay bodhisattva can't cross the river-make a zodiac sign"?

I think any one of the 12 zodiac animals will do.

Because, to put it bluntly, zodiac animals are all animals, still in reincarnation, and they are stupid and don't even realize it. How can these poor beings really help other lives when they have to repay their karma and take care of themselves?

Or "Buddha" and "Guardian Bodhisattva"?

Unfortunately, those things are only the beautiful wishes and longings of future generations at most, not the things in orthodox Buddhism. To put it bluntly, it was made up by later generations, blindly superstitious. The zodiac, horoscope, divination and fortune-telling in serious Buddhism, the so-called "life Buddha" and "guardian bodhisattva" have nothing.

Can you understand this explanation?

If you don't know how to ask me, I hope it will help you.
