Ohh My! How lovely your faery friend has set you with some materials on a healing spell,,, but it all depends on the type of healing you're seeking, for example those materials above seems like a broken heart healing spell? or an emotional distress healing? Or even sickness? Thats all i can guess… but if its either or, they all work the same in a spell….
So the white candle stands for purification, if you like you may grab the rose petal, and on the petal write something inspiring to yourself such as "this petal is to heal my broken heart" or "this petal will heal my stress away" once you done writing something get a white saucer plate, place the petal underneath the saucer plate, take the white candle and place it on top of the plate, light the candle as you meditate a bit,,, now with the white feather, gently while sitting in a comfortable position with your eyes closed, take the feather and run it smoothly on your forehead, (imagine nothing but pure light entering your body), again run it smoothly on your right eyes (imagine you seeing nothing but glorious life), again run it smoothly on your left eyes (imagine you being free from all sadness, and realizing nothing but happiness), and finally run the feather around your face (imagine every pain disappearing, but picture yourself surrounded by joy, nothing in life can interfere now).
Once you feel relax, imagine your faery friend blowing behind your neck…. right there you should fall in deep meditation, continue thinking of nothing, notice what you feel, and dont let your mind wonder off (unless its in the deep forest, lol) but dont think of any other thoughts that has to do with "life worries"…. Once you're all done picture yourself being shield by this white light covering you as a blanket, stare at the flame and let the flame burn away the cause of your distress, and from there give thanks to your (spirit) guides, than relax and let the white candle burn down til complete, once completed you may look at the wax for any foretelling, (sometimes you might see faery wings, or angel wings, or some human body form with a melted candle wax over it< this all means that you're are now protected or healing) if you cant foretell anything with the left over wax, no worries, you can throw it away or bury it in your backyard, but the rest of the material such as the red rose and white feather, put it in your gold purse, which is something you'll have to carry everywhere with you.
Btw just so you know, I had a similar dream and figured out this spell because of my godmother, but you may be creative, if you feel this is not the right spell, close your eyes, think of NOTHING, ask your faery how would he/she prefer to have this spell done, than relax and listen or see what images you get in your mind to be inspired wit your own spells, any spells you create is your magick and it CANT go wrong for as long as you follow 3 basic rules… 1. never use another persons name…especially on love spells, 2. Dont do any spells on bad intent, 3. and dont use any upside down signs… other than this you should be fine, just have faith…. Peace and Blessings.
