It's impossible to move through our day to day life and not come home with spiritual dirt on us. Uncrossing work cleans us off and elevates us out of that negative space. It's most beneficial if you're being worked on negatively by another practitioner. The herbs and powders work to break curses and hexes while refreshing and blessing you. It should be noted that if you believe you are the target of a hex, to seek out a reading with a professional to confirm or correctly diagnose what's happening.
It's strongly recommended to pray Psalms 51 3x over the candle while you're doing the work.
