Can spirit boards, pendulums, and mediumistic descent be treated as one method?

They cannot be regarded as completely identical. Outwardly all may seem to obtain answers, but actual use and the energy sources I understand still differ.

Abroad, I watched friends consult a spirit board. It moved and circled letters that formed answers, somewhat like a spirit-plate game. I did not receive a reading, and the friend's result did not come true. One experience cannot determine all boards' accuracy. Religiously, I regard such spirit invocation as riskier, so novelty should not remove questions about sources. Strong fragrance in the street also made me wonder about unusual sensations, but I did not establish that it caused hallucinations.

Regarding pendulums, Dao Jing shared seeking a reading after a sound system turned itself on. Users generally define movement directions before interpreting. I understand this through resonance among one's spirit, intention, and movement, and also watch for unconscious hand motion. Spirit writing, in my understanding, involves divine energy expressed through its implement, differing from one's own spiritual feelings.

This is my comparison of religious tools, not scientific testing. I wondered whether Guanyin interacting with a pendulum could be studied, but that remained an idea without a completed method. It cannot serve as operational instruction.

I also explained spirit writing through the operator: a pen itself is not spiritually communicative. Someone resonates with a deity and expresses perceived content through a pen or another object. I use resonance among person, medium, and energy to understand chess divination too. Seeing an object move cannot erase human involvement or establish that every tool is identical.
