What's the use of the fortune teller asking me to put some dirt in the jar in my bedroom?

The fortune teller told me to put some earth in the jar in the bedroom for the peace of the building. In geomantic omen, temples before and after gods belong to remote places, and it is not good to have temples and churches near houses. These places are places where immortals lift their feet, which will disturb the nearby gas field or energy and affect people's ecological environment.
