What role does coarse salt play in geomantic omen?

Raw salt is divided into marine raw salt and rock salt. Most sea salt can play the role of evil, and sea salt can be divided into fine sea salt and coarse sea salt. Because there are many impurities in crude sea salt, it must be refined to eliminate evil.

However, the efficacy of sea salt varies with different items. For example, sea salt can purify crystals, but it must be mixed with spring water or good mineral water.

For another example, the role of sea salt in cleaning houses must be matched with whole grains.

For another example, sea salt can ward off evil spirits, but clean salt needs to be refined with wormwood.
