This piece holds the power of your djinn-double that lives in the realm called Grine. Each time a new human is born, there is a djinn born in the Grine. I'm not going to get into the why's or the particulars, but it has something to do with the balance of power between the mortal world and spirit world. Either way, this piece gives you a connection to your very own Grine and I mean that literally. It will manifest the Grine Djinn that was born when you were born so that way the two of you can live in existential harmony. Your Grine is able to grant wishes, of course. When you make a connection with the Grine, he will grant you everything that you want. There is no need to tell him what you want because he is a part of you and you are a part of him. He (or she) already knows and you can consider it taken care of.
Instructions-- You can simply wear this piece and the energy will awaken your Grine. If you want, you can also meditate with the piece, which will speed up the bonding process.
