This isn't really a spell, per se, and so it doesn't require divination or sacred space/magick circle. It's more of an exercise, designed to banish negativity from the body. I do it whenever I'm uptight or angry in order to get back into a rational state of mind.
This exercise really isn't religion-specific, and really isn't original, either. I've seen it everywhere, but not custom-tailored to Wicca. That's what my contribution is.
Good Luck and Blessed Be.
