To purify yourself from negative thoughts, bad habits, or dark experiences, use a potent mix of equal parts bloodroot, thistle, and lemon verbena. Start by grinding the herbs in your mortar and pestle and burning them in your censor. State aloud in the direction of the smoke each thing you want to eliminate. Watch each negative item drift away from you in the smoke. Make sure you grind enough of the herbs to last through the rite if you intend to eliminate more than a few things. When you have voiced everything, waft the incense toward yourself and cleanse the last negative remnants away.
