Something I have to say. There are too many role players and role playing spells that I've seen on here. I'm a novice, and I'm seriously trying to learn magick. I've had people who are just not serious message me about serious questions that I've posted on here. I need a teacher who is experienced in both black magick, white magick, and mind power. Also, I need to know how to tell which spells are real and which ones are fake (minus the ones that are insanely obvious, like the one I found on how to make a horcrux).
My best opinion is self study.It is the most reliable way you can find :)
All you need to do is research on the craft.It is'nt that hard to distinguish between fake and real spells,all it needs is common sense.
As for teachers,many serious practitioner would not advertise around or invite students,some are even pre-occupied while others busy.But you may mail people for guidance on a subject in hand.
I wish you luck on your future endevours :)
