Ask a superstitious question, do you need to see the place clean when renting a factory? I'm afraid of the influence of those dirty things on people.

This is not superstition, because human flesh is invisible to the naked eye, so everyone becomes superstitious about what is invisible. All beings in the room are normal, so you can recite the mercy mantra and sprinkle nectar. You can learn the Mercy Mantra on the Internet by yourself, or you can recite the Bodhisattva Nanwu Guanyin. You don't need to find someone else to see it. Looking for someone to see things is superstition. Buddhism does not advocate it. Those are pagans.
