Do you believe there is white and black magic?

• I've heard stories that you can be affected by black magic without being guilty of it. It is said that the effect of black magic can be transmitted from the knee joint to the knee. They also say that it is important not to lose hope and faith in a better tomorrow. Anyone who believes this, asks for help from the white magicians. Is there really white and black magic?
