You know how its said that reality is ever evolving or ever shifting, for some people the 'classical' meta paths could still be true. Thinking about those beings you see in folklore plus other references, the practices that treat it as 'closer to the physical' and concepts or ideas like 'special overhangs in the wild' etc.

Are there any reading materials on the 'traditional' or 'classical' meta paths and what do they mainly focus on?

I just bought Jason Louv's "John Dee and the Empire of Angels", about how Dee and Kelley received angelic messages that taught the Enochian magical system. That might be a topic of interest to you, with your motivations to operate on the light end of the spectrum.
