Why is there a bad spell on some people?

It can feel that way, can't it? There are no bad spells, but we understand that people from some cultures strongly believe that there are. If you allow yourself to believe that spells are involved in how friendships and relationships develop, you will develop great skill at interpreting whatever happens in a way that supports your belief. Talk with trusted family and friends. You can see things clearly without having to conclude that spells are involved.
