Magic has many forms all of them share in some fundamental way.
There is magic of the liar
There is magic of the trickster
There is magic of the brainwasher
There is magic of the dark art
The liar is a propagandist, the cunning use of language to throw people into states of deception and the astrologer and soothsayer. The trickster is the stage magician, the Hollywood film maker, the exploiter of optical illusion and practitioner of science in ways that contradict apparent logic to the uninitiated eye or utiliser of scientific phenomena to deceive people. The brainwasher will know how to access the deeper faculties of the mind, utilise hypnotism and repetitive techniques including the lies and tricks to confound the brain to be convinced the lie is in fact a truth, and The dark artist - communes with demons to possess target people, and act upon a contract to sow discord through whatever means the demons know, it is them operating in their own normality which to us may seem like something mysterious or miraculous.
All of the magic form are lies - but that does not mean all of these lies do not have physical realities … the reality of black magic is as real as hiring a hitman to kill your target, except the hitman is hidden from view. By evading the demonic presence magicians will claim to be initiating whatever they are doing through their own power … and not the help of the shaitans. This is to clear up any confusion in this matter.
Of course it’s important whether something works or not! People kill and die for superstition thinking it works! There is no difference between those practices and practices of every other religion…people think it works! It doesn’t!
And I would submit to you, all religions are made up to serve very specific purposes of grown ups!
