What you will need:
1) white candle and lighter
2) prayer of healing ( I generally use Hindu mantra of shiva)
3) picture of person
4) silver mirror and bowl ( Even silver shine is good enough)
5) Place you consider holy.
6) holy water.
*Note* Please make sure to take shower and meditate before doing this. Also charge the candle for 3 day straight and cast the spell of new moon for best result and have faith.
Start by carving you personal symbol which represents you on it (I personally have my symbol which I saw while meditating long time ago), than take the candle between your palms and rub it in like you are trying to thin it, while doing this say the prayer of your choice, and repeat the prayer word for word till you feel you are out of breath. And get warm feeling in your hand not of friction but of candle is give off heat. Now hold the candle in between both of your palm like you are saying Hindu Namaste, and speak on it and say the name of the person you wish to heal and make sure your breath is blowing on the candle so keep your hands close to your mouth. As you are doing this you want to make sure to channel you intent and into action, don't question what you are doing. After 3 days of doing this on the new moon, place the candle in the silver bowl and add little bit of holy water, just enough you don't want to fill the bowl, now take silver mirror and channel the light and reflect the light upon the candle. While you are doing this say that prayer 5 times in your head and one time out loud (but don't scream). Now take the candle and light the candle at place you consider holy like alter etc... And let it melt completely don't put out the candle. Take the wax after an offer to the gods/goddesses you worship and send it off into lake or river or even stream.
PS: Please be careful when you use fire. and have supervision if you are young thank you.
