Sometimes spirits attach themselves to an individual rather than merely haunting an area. The spirit may speak through the individual, refusing to leave. Encouraging or forcing them to leave is a shamanic technique. However, should you find yourself dealing with a case of possession without an exorcist in the neighborhood, the following spells may be attempted. In general, you will still need a ritual assistant to help achieve your magickal goals.

Here are some general guidelines:

• Use intensive cleansing methods to purify the area.
• In addition to whichever methods are employed ring bells, cymbals and sistra loudly.
• Invoke benevolent protective spirits, like Archangel Michael, Kwan Yin, and/or Isis.
• Draw up talismans of protection.
• Summon the demons demanding that they come forward and depart.
• Look for signs of departure.
• Dramatic spirits will let you know they’ve gone. Otherwise use divination techniques to determine whether your methods have been effective or, if not, what further action should be taken.
• If you’re sure they’ve departed, burn the talismans.
• Mix a teaspoon of the ashes into cooled boiled spring water. Have the afflicted person drink it.
• Close the ceremony.

In traditional Chinese belief, what we call demons may actually be a manifestation of excessive Yin energy. This can be neutralized by applying the opposing force: extremely potent yang energy. The following serve as demon/yin repellents:

• Firecrackers
• Mirrors
• The crowing of a rooster
• Swords

Reading sacred texts and philosophy books is also believed to send malevolent spirits on their merry way because these create order, in which demons (which crave chaos) cannot thrive.

It is also traditionally believed that low-level malevolent spirits can enter the body through food. This is the source of many fairy tales where evil is swallowed. Certain foods guard against this as well as expelling any previously swallowed demons. The most powerful include the following, and can be added to food to expel and also prevent demons:

• Ginger
• Garlic
