It all comes down to belief.
Christians are afraid of it because of a lot of different beliefs.
People don't lose their mind whe 'studying the occult'. But some take it too seriously and lose themselves in a lot of fabricated beliefs that can lead them down a lot of different holes.
Drug addiction, depression, loss of order in life, schizophrenia, etc.
It's a hobby really. After some years of actually trying this shit all I can say is it's all in your head, but there's something beyond what we can even grasp. Books written by humans won't lead you to understand it. Just like in science, we can only make models of it and think of it through these models. It's really complex, but most of occult stuff comes down to shit humans make up for various reasons. Please be careful. You could also spend time studying math and getting good at natural science to someday make a real difference in the world and make it more magical. Sorry, but there's no 'magick' in any of these books.

This idea that everything is 'in your head' is bullshit. Some shit that happens cannot possibly only be in your head if you are seeing or hearing things that you DO NOT expect to see. There is no way that the elites, the CIA etc engage in occultist practices for funzies and a good time. This notion is complete bullshit.
