Magic as we know it today, done by magicians, is illusion. It's trickery. However, Aleister Crowley, really brought the spelling "magick" to the forefront to set it aside when referring to non-illusionary magic. There is both. There is real magic. I will not tell you how to get into it. Before you start really looking into it...just think for a second about where this power really comes from.
God never told us the devil doesn't have power to offer humanity.
