I have seen a several different methods in regards to salt divination.
The first is by throwing the salt into the air and interpreting the way the salt falls to the ground and the pattern it lands in.
Another method is leaving salt and a bit of water out in a bowl and interpreting the pattern that is left in the bowl once the salt evaporates.
Some will throw salt curstals into the fire and interpret the pattern of the flame upon doing this. The interpretation is based on the color, speed and direction of the flame. This is a form of pyromancy.
In my travels to research how this is done, I also came across the following method from Llewellyn. It immediately brings images of the zen sand gardens to me! :)
"Divination with salt or dry sand. Pour the salt or sand into a square or rectangular tray to a depth of about three inches. Hold a pencil loosely in your hand, with the point at the center of the substance. Relax, close your eyes, and state your question. Let your hand move of its own accord until it stops—and no longer than three minutes. Open your eyes and look for symbols or letters among the markings. Some common examples: “Y” for yes; “N” for no; “P” for perhaps; “X” for love. A long line for a journey; a short line for a visitor. A large circle for misfortune; a small circle for news; a triangle for success; a square for obstacles, a heart for love, a broken heart for parting a parting. Read other symbols in relation to your question."
Now a variation on this one above from Llewellyn is to use your pendulum to do it. So set up the box of salt in the same way but then hold the pendulum so that it just touches the salt, focus your attention and see what you get for results.
I've searched through the internet and while I would love to tell you I found sites on how to interpret your results when using these methods I must say I came up with nothing. *sniff* However, given what I know about divination I would look for patterns in the sand. Look for any symbols that may be meaningful to you. If you don't see anything at first, quiet your mind and let your intuition take over. Have you ever stared at something for awhile until things get sorta blurry, then they can start to blend and look different? No no no don't tell me I'm the only one :P C'mon admit it you have. LOL :))) Even if your eyes are just tired. This can happen then. Look into the salt and try to let that happen. Try not to blink and let your mind wander. What do you see now? Let me know how you do! :))))
