You probably know that there is power in a name. In other words, if you drop someone’s name, and other people know that person, then you’re likely to get further than if you didn’t mention the name at all. That name has the power to open a door.
On the other hand, sometimes dropping a name can have the opposite effect. You end up getting stonewalled because the name you dropped is unfavorable to that audience. That name ends up closing the door instead of opening it.
Similar to how human names have power, spiritual names have power. Except, they have even more power. This could be very dangerous if you are using the names of evil spiritual beings. You could be opening the door to allow these evil beings into your life.
Therefore, similar to how you need to be careful when dropping human names, you need to be extra careful when you use spiritual names.
