Sit in a quiet place and clear your mind of everything you can.
Take the amethyst (or fluorite)and hold it in the hand that is closest to the hurt.(if the pain is in the center of the body hold it in your writing hand.
Imagine a soothing light collecting at your feet and draw it up slowly towards your head filling every part of the body.
Whilst doing this say silently the following verse:
"bright light, shining light
heal my hurts with all thy might."
Repeat this as you move the light up through the body.
When you reach the top of your head expand to fill outside the head with light for about a foot.
Then return to where the pain is most concentrated, push all your healing energy into this area.
If this doesn't work the first time then repeat. You should feel better soon.
to end the spell repeat the verse again but finish with "so mote it be"
