Hey, baby witches, hatchling mages, and second instar sorcerers...
If you see somebody on the Internet claiming they're setting up some kind of spiritual/magical academy, or looking for worthy pupils to teach, or - and especially - looking for a worthy pupil to teach, you need to be very wary.
Literally anybody can claim that they have all kinds of deep, true spiritual knowledge. Literally anybody can scrounge up a few mystical books and learn just enough to make it seem like they know a lot to someone new to magic and mysticism. Anybody can whip up some conspiracy theory to explain why the stuff they just pulled out of their bum three minutes ago isn't accepted by academic scholars and mainstream religion.
It's always worth asking yourself, "How do I know they aren't lying to me?" And don't just go with "I can just sense they're telling the truth" because it really does not work that way. What you might be "sensing" is their conviction in their own bullshit. Or they might be a really good liar. Or they might be saying stuff that feels true because it seems to confirm your own biases.
Also, if you see somebody telling you that reaching your highest magical potential means doing some kind of sex magic, or offering to teach sex magic to beginners, run. This person is a sexual predator.
I recommend ESOTERICA and Angela's Symposium to start getting a grounded view of religious and spiritual history, which will make it much less likely you'll fall for a scam.
Also, remember that at the end of the day, vital spiritual or magical knowledge is not locked away with any individual person or even group. The main thing that any specific person or group has is their own take on things, which generally as subjective as anybody else's.
Just because information is commonly available doesn't mean it's automatically bad or wrong. Like yeah, you do need to be critical about what you read in books or on the Internet, but you need to be just as critical with an actual human being claiming to have the really deep secrets.
