Malachite is a semipercious gemstone with bands of lighter and darker green. To make a safe-travel amulet, obtain a peice of tumble-polished malachite from a rock shop or an insent peice of malachite from a jewarly shope.
To charge the amulet, stand with it cupped in your hands, then ground and center yourself. Acieve a mental state of alertness similar to the state you want to be in when you are driving your car.
Breath energy into the stone and speak in a strong decisive voice:
Safely go by foot and air, safely go by road and sea. Safely go ere I get there. As I will, so mote it be!
Carry the stone where you can see or feel it as you travel. In you car, affix it from the rearview mirror. If you are using malachite jewalry simply wear it until you arrive at your destination.
