To cast, simply recite the spell with the full weight of your energy & intention behind the effort.  You can recite out loud, or through telepathy (your mind).

If you feel you need candles or other draws like incense or stones please use them if they make you feel in the appropriate state of mind.

Or if you'd like to bind the energies of the spell to a stone for boosting purposes use these instructions with a candle:
Pass the rock over the flame three times after the spell is recited.
Keep the rock near you to have the spell surround you.
You can use the spell as much as you like!

Washing of Soils

Take this heavy burden of illness

Wash away that which I know is poison

The bad energies circle me and prey on me

Wash them away so that I may find inner peace.
