Now the internet is full of people telling you how to do a spell for this, a spell for that but it’s not that easy or safe.
When you do a spell, in order to work you have to call an entity and no protection can help you 100%. The problem is that an entity will attach itself to you and feed off of your energy and is not that easy to get rid of it because you called it though the spell and it’s like you agreed for it to be there.
Without that entity the spell won’t work so in exchange they want total access to you and your energy. And it’s the same with any entity whether you call it ghost, demon, angel, god or goddess and feeding off of your energy will affect your body and health.
