This "spell" or rather ritual is an interesting exaple of how can Double action candles be used. It's supposed to be done on New Year, but of course not reason not to be done whenever needed :)
Simple and very effective, simply place double action, black - white, butted candle horizontally on a plate, and dress the black half with some Banishing or Uncrossing oil.
You may say something along these lines :
Lord, to You I cry, set me free of all evil, malice and snare s of the wicked people and spirits. As the candle burns, wax melts in presence of flame, and as smoke disappears, may all ills that trouble me be-gone ! Amen !
Then dress the white part, from top to middle with some Blessing oil or Holy Anointing oil, or Special oil No20, saying something along the lines:
I / We pray to You Lord, Merciful and Human Loving G?d, Be kind unto/to us sinners, Forgive us our trespassing, and be kind to us weak. Give power to our spirit and guide us on righteous paths . Remove obstacles and stones from our way, and send us Your Blessings, so we can live happily, praising You always Lord. Heal us, protect us and, how much we need, help us provide Lord. For the Power and Glory are eternally Yours. Amen!
This spell simply does what suggested in above article, cleanses bad and draws good instead. It is very beneficial to be done anytime, perhaps on full Moon, but certainly y well suited for dark winter days, ending of one Year and beginning of another. Alternatively You can burn candle vertically, same way, just in that case, make sure that the black part is first to be burnt.
***The phrase " butting a candle " in Hoodoo reffers to cuting out the wick from the bottom of the candle and placing it upside down, usually done with double action candles.
Hope You might find this useful, and many Blessings in 2012th :)
