Can the pendulum become an element of tarot cards?

No, the pendulum can only be used for divination and can't be used for other purposes. I wrote my tarot card opening ceremony for the landlord's reference. Prepare fire (candle), wind (aromatherapy, which can't be replaced by a knife), water (pure water or tap water) and earth (salt or ore, crystal) at the four corners of the table, wash your hands and intuitively choose the brand spirit.
