With your mortar and pestle, grind together 1 teaspoon of Rosemary and 1/2 teaspoons of Patchouli while concentrating on safe travels. Knead your herbs into a handful of no-bake clay. Flatten the clay until it is no more than 1/2 inch thick.
Carve symbols of protection [Triquetra, Eye of HOrus, and so on] directly onto the clay with a pointy object. Set this aside and grab your stone of jade. With the jade in your dominant hand, charge it with an intent of safe travel and focus on your journey, free from obstacles. Press your charged stone into the center of your clay. If you feel that it may come loose, adhere it with a few drops of glue.
Place your charged amulet/charm between two purple candles. Light the candles and enchant all of the ingredients together by repeating the following:
As I travel and venture about
Regardless of my choice in route
I ask for protection, be it visable or unseen
With no mishaps, please intervene
By herb, stone, and clay of protection
Return me safely home, in complete perfection.
Allow the clay to dry. You may store it in a purple cloth bag, and carry it on you, or punch a small hole in the top, to hang it in your vehicle.
