I first learned about wish rocks years and years ago from an article about them I read in a magazine (sorry, I forget which one) by (I think) Pamela Redmond Satran.
A wish rock is a rock that has a stripe that goes all the way around the circumference of it. It can be thick or thin, even or wavy. Sometimes, if you are really lucky, you see double wish rocks-2 lines going around the stone.
When you find one, you can hold it in your hand, infuse it with some wishes (just speak your wishes, either aloud or silently to yourself, to the stone), and that’s it! Carry it in your pocket, put it on your bureau, or whatever you like.
You can make a wish rock for someone else. It’s the same process, except that you make the wishes for the other person.
What a cool idea, right? Kind of like affirmations. Give it a try!
