About Salt

"Salt, as in ordinary household salt, is a powerful absorber of psychic energy. It doesn't channel this energy but absorbs it and holds it instead and it is this central property which accounts for its many different uses in magic.  

Protection 

Salt has always been used as protection against psychic attacks, and to disable unwanted psychic phenomena.

Ordinary salt may be sprinkled across thresholds and around the perimeter of dwellings, inside and out;

Salt mixed with sand is used for forming magic circles;

Rock salt crystals can be added to "medicine pouches", carried in pockets or worn in a small bag about the neck.

Sprinkling salt around someone's bed protects from unwanted night time visitors and reduces the likelihood of unwanted spontaneous OBEs.

Purification 

With salt's extreme ability to draw away remnants of psychic energy, including "ghost manifestations" of many different kinds, salt has always been used for psychic clearing and for purification.

Magicians and priests routinely prepare for ceremonies by taking a bath which contains salt as one of the main ingredients;

Magical objects and crystals are cleansed by immersing them in salt water;

Bowls of salt may be placed into a room to absorb negative energy or psychic energy disturbances."
