Spirit water is used primarily for personal cleansing, but it can be used to cleanse your sacred tools or sprinkled around a room to cleanse the space…. As with smoke cleansing, remember to pay special attention to corners. Spirit water can also be applied topically to cleanse the body of spiritual pollutants. For pollutions that affect sexual health, apply the water to the genitalia and wash downward. Some also ingest a small amount of it if they are sick or suffering the effects of pollution or curse.[1]
You can also heat spring water to produce steam that can be used for cleansing. Place the water on the floor between the legs of the person being cleansed and let the steam rise up the body when the water is heated. You can also use it as a spiritual cleansing bath….
This method [of making spirit water] employs sacred herbs and therefore can be much more powerful. As with smoke cleansing, I recommend using either herbs your ancestors used, and/or herbs that grow naturally in your area. When making spirit water, always use an odd number of herbs I use juniper (commonly used by Mongols), Asian thyme (commonly used by Manchus), and marsh labrador (commonly used by the Amur).
Heat some water until it boils and place the herbs in it. As the water continues boiling, make a prayer to your spirits or gods, and ask them to pass through the water to bless, activate, and empower it to be used for cleansing and healing. Just as using water from nine different springs can make your spirit water more powerful, using nine herbs that are sacred in your culture or land can increase its power when made in this way.[2]
