Whenever someone asks other people to prove to them that magick works, it always amuses me.
If you cannot accept magick, that is your problem, not anyone else’s.
If you always throw away any new magick that doesn’t WOW and AMAZE you with immediate visions and super energies and billions of dollars first time, you’re going to throw away a lot of magick and are going to have trouble getting any of it to work. Magick is a process. It takes time and energy from you to make it work. Sometimes you can just chant and wait a bit for an opportunity to come your way (but even then you need to make yourself open and able to receive), but with Enochian magick especially, you need to put in your half of the work. The grimoire tells you exactly how to do this.
I’m not trying to pick on you in particular, but this sort of attitude is not uncommon, and it prevents people from discovering all the wonderful things that magick can do for you.
If you are curious, I have performed the first ritual from this book, and I share some of my experience here.
