I agree to a certain extent. Real magic is about using spirits/devils to do your bidding. Its also about controlling other people.I think what is similar to occultism and Wicca is the lie about magic. Human beings have no power to cast spells or make "magic". satan fools some into thinking they have power, but it's a lie which is all satan does.
Black magic has been used for thousands of years, the Egyptians were masters at it. It evolved into what later became know as Mesmerism, then Hypnosis in the field of psychology. The Egyptian priests use to put every child of a certain age under hypnosis, so later on in life that person could be put under a trance more easily. While under this spell the child would utter things that were said to be from the gods. The priests knew better though, it was a way to make the masses subordinate. They also used natural and scientific phenomena to control the masses, the priests knew astronomy and kept it from the masses, they could " predict" when solar eclipses and other astral alignments would happen, and claimed it was messages from the gods. They'd use this to whatever ends they chose.
Angel/devil magic involves rituals that supposedly summons devils. I don't believe these rituals are necessary. People can contact devils anytime they choose in my opinion.
