I feel Witches Stones, also known as Witches Runes or Oracle Stones, are a good place to start. Although the stones themselves have set symbols on them, interpreting the layout and full meaning of each stone requires meditation. Witches Stones are also unique to each practitioner. Although there are some common symbols used in beginner or commercially available sets, as you work with them you will find that each stones meaning will alter slightly and the way you interpret them becomes unique to you. You may also find yourself expanding the number of stones you read with.
Below are ten symbols you would commonly see used on witches stones. Personally these are the symbols I would use if putting together a set for someone who was interested in learning them.
Wyrd - Fate, destiny, the unknown, that which is yet to be decided.
Black - Negativity, bad luck.
Spears - An argument, dispute or confrontation.
Moon - A change, usually within 28 days (one moon cycle).
Sun - Growth, prosperity, abundance.
God - A man or a leader like/providing force.
Goddess - A female figure, a protective force or a care giver.
Birds - A message.
Corn - A work or career situation, or hard work bringing rewards.
Rings - A partnership or relationship.
Usually to use the stones I would do either a three or seven stone casting. Three stone castings are good for getting a feel for the stones when you first start working with them, they are also great for quick answers and readings to uncomplicated questions and scenarios. Seven stone castings are great for general readings, or more complicated queries. Both are performed pretty much the same way.
Pick stones out of the bag , hold them together in one had 4-6 inches above table and then drop them. Look at the stones and how they have landed. Some stones will have fallen close to each other , these stones will relate to each other. Some stones may have landed upside down. Some readers will simply turn them over and read as normal - (this is my own chosen method), some will discount them all together, and some believe that it indicates the opposite of the meaning indicated when the stone is the correct way up.
