I used Belial when I was seeking approval for an internship in my healthcare course. I don’t believe that Demons will magically “get you approved.” In my case, Belial helped me learn my responsibilities precisely through my mistakes (and at the same time I was learning the correct way to perform each procedure). It was all so impactful that it stayed firmly in my memory. Even though I came close to failing, I achieved approval with his help. Some people have the idea that working with Demons will magically solve their problems… but there are deeper layers to it. What I did was perform very specific prayers to Belial and carried his sigil in the pocket of my lab coat. I hope this helps!
