Bad boys, bad boys, watcha gonna do? Watcha gonna do when they come for you? There are a lot of things that people do to ward off evil spirits or to protect their home. They may hang horseshoes on their door, or put up some wind chimes, crosses, evil eye Mezuzah or even place garlic cloves around their neck. However, there is only one method that is guaranteed to keep evil spirits from entering your house. It is the power of your intention. If your intention is relatively good, then you'll have a great deal of peace and prosperity. If your intention is bad, there will be only so much you can do, before the evil spirits come for you.
