Good point, I remember that from years ago when I first had it and worked through it avidly. I read a PDF of the Mystic Grimoire years ago, but could never find a hard copy that was any kind of reasonable price.
Next time I have space and energy, I may try calling on that spirit for more enlightenment. This is an exploratory and experimental work with the ultimate purpose of finding ways to access lost grimoires, I’m currently paddling in the kiddie’s end of the pond, so I’ve now added “evoke/contact guardian spirits first” to my list… cheers.
