My sister and I beleive that someone is using voodoo on her,how can we stop it?

Hello there my dear, And why would you believe that they are using “voodoo” in particular on your sister? Voodoo is a religion, much like Christianity or the Muslim faith… and not a catch all term for black or evil magics, regardless of what modern media would like you to think to the contrary…. Anyway, if you have reason to believe someone has put a curse upon your sister, perhaps the following will help: A Spell to Counter Another%u2019s Magic If, for some reason you believe that another person is using magic in order to adversely affect you in some way, you can make use of this simple spell to remove their negative influences. What you will need: Two teaspoons of almond oil Rosemary essential oil A mixing bottle A sheet of white paper A black ink pen A white altar candle A purple taper candle A fireproof bowl Place three drops of the rosemary essential oil and the two teaspoons of almond oil in the mixing bottle. Charge the mixture by rolling the bottle between the palms of your hands, focusing your thoughts on the purpose of your spell-weaving as you do so. Set this aside. Light the white candle, focusing on the flame. As you do this envision whomever is responsible for the negative influence upon you growing smaller and smaller within the confines to the flame. Anoint the purple candle with the charged oils, drawing the oil away from you as you do so. This will help to redirect the negative influences away from you as well. Now set this candle aside. On the white paper write the words, %u201CAll blocks are now cast aside.%u201D Fold the piece of paper in half three times. Now light the purple candle and use its flame to set fire to the folded paper. Place the lit piece of paper into the fireproof bowl. Focus on the flames, repeat the following aloud three times: %u201CAs this paper burns away, Elements please hear me pray, Turn back the ill will sent to me, And send it on its way.%u201D As the flame dims, see the ill dissolving with them, then bring the session to an end by smothering the flame the rest of the way.
