I am fairly new to the magick world. For the last couple of days I have been trying to do this banishing spell and it seems not to be working, don't know if I am doing it wrong or if its that I am not powerful enough to do it.
As a beginner, you should not start with these spells. They may backfire you .you should learn the basics before casting spells. As a beginner, you can cast spells like healing or protection spells. Once you are experienced in magick, you can cast spells like the one you provided. There is a 'beginner's guide" which will help you.Hope this helps!
