I wouldn't say miraculous. I think supernatural, or more apt demonic. I think demons use the occult to take over people, or manipulate people.
Why be pinned down by the term and ignore the usage? In the East, mantras and yantras are simply acknowledged as methods for focusing and directing various types of power. A huge part of their traditional use is in medicine and healing. Used for evil purposes, the same "tools" become "black." Even prayers can be - and are - used positively an negatively.
Think of modern medicine technology referred to as "physics." Then think of a nuclear warhead referred to as "physics." Same single-term comprehension problem.
While I would like to believe in angels, but do not, I do not believe in demons either. I believe there is a supernatural, but like it’s description, it’s unknown...as God wants it to be. I know throughout history, many people have wanted to and have said they did or do know the supernatural. I don’t believe them. It’s just one of those things that cannot be satisfactorily proven to any real number of people over time.
