The Legend of the Bell
Across cultures, continents, and religions, bells have been rung to banish evil spirits. It is considered good karma to have a bell on your door, which acts as a beacon for welcome news and prevents bad energy from entering. Many motorcycle riders attach bells to ward off mishaps and mechanical failures. A Guardian Bell® carries twice as much luck when purchased by a friend or loved one and given as a gift.
