Freemasonry is a secret society.
All secret societies are satanic.
Freemasonry is the most well known secret society.
Freemasonry itself is a satanic organization, even if some of the Freemasons seem otherwise like "good guys."
Here is an overview of Freemasonry:
Did it teach spells (curses on people or rituals for favors) specifically, or were they just symbolic mumbo-jumbo?
I saw some AMORC (Rosicrucian) neophyte manuals and it was excercises to develop aura seeing ability and communicating with the mind amongst other things
Contacting evil spirits. Please stop defending satanism. It leads to being hellbound.
Where have I defended Satanism?
Understanding symbols and nature are one thing, but what you describe is necromancy, and I certainly don't condone it.
That said, I've read Satanic Grimoires before. All the fluff and "eye of newt" junk is make believe. Real witchcraft feels like an instruction manual on how to be a sleazy lawyer or crooked used car salesman.
I wouldn't know what real Satanism was if I assumed it was just hocus pocus. In reality, it's a cold and dirty thing. When reading real Satanic works, you feel like a demon's cold paws are clawing at your spine. I don't advise anyone to endure what I have, so it's best to steer clear of all of it on the off chance a toy manual might let slip some of the real stuff...
So, don't expect me to link to any of 'em.
Not everyone can read the real stuff and get away unscathed and untempted to use those "lessons" it provides. Luckily for me, I'm lazy and lack all ambition to begin with, so I'm effectively immune from the temptation to use the Grimoires. I'm a specialty case, because my Love is the Truth, not Power -- which is all those power-hungry books are written for anyways.
They're useless to me other than the novelty of it all...
