Since I came on to this site some ten years ago, I am often surprised by the number of teenagers (and some much older) who believe that spells are magic. They are not magic. I have worked with magic for well over seventy years, and I have never cast a spell!
A spell is a ritual attempt to obtain a magical result. Magic is changing one or more things into something different.
Of course, you may believe anything you want to believe. But a belief does not make it true!
