Red brick dust is a simple yet powerful protection against black magic or other forms of evil. It is said that when red brick dust powder is sprinkled around your house or business establishment, no evil force can enter the premises. In south India, we can see that all temples have walls that are painted in red stripes. This paint is supposed to be made out of red brick powder. You can also mix this red brick powder in water and sprinkle it around your house. This practice is found all over the world and is not unique to India.
