USES: keep it on your altar, carry it with you, keep it in your vehicle, give it to the person you made it for if it wasn’t made for yourself.
The most powerful manner of use is to keep it with you at all times, even at night placing it on your nightstand next to you or under your pillow or mattress. But if it is easiest to just keep on your altar or other designated sacred space, then that will work perfectly as well.
