Well from a strict point of view, reading this stuff would seem pretty odd, but I have been through the old wizards spell book we are not acting out a rite here. We are interpreting some words, reading them is not putting your soul being into some scripture and seeing where it takes you, that is left up each your own ability. People read the bible all the time, but it doesnt turn them all into saints, as such what this tripped out dude was saying is not going to shade some evil omen over me forever for reading it. That is superstition. Intellect has lost control at that point, and guess what... you wake up and everything become clear again.
In my eyes this is all a form of magic, even as I type this to you.
Just to trying to dispel some possible fears, but then leaving all possibilities open
