If you know the spirituality of crystals, please come in.

At best, the magnetic field is relatively clean

But there is no lack of assimilation by the surrounding magnetic field. I don't know if it suits you.

Think too much about divination

Crystal is a magnetic field, big or small, hot or cold. I have never heard of spirituality.

Only special secret instruments or blessed people may help you.

Pendulum only uses the mutual induction of magnetic field, and any object placed next to it will have an impact on the magnetic field.

It's not good if the magnetic field is too noisy.

A bunch of crystals in my house are just too miscellaneous.
