you see a similar approach in ancient alchemical texts- the images are symbolic metaphors that transcribe philosophical thought to those who have sufficient knowledge to understand what they're looking at. Otherwise, you're just looking at a bunch of chicken scratch, nudes and moonshiners.
@lucifargundam pretty much yes.. i mean even the words alone are hard enough to follow without domain and time-period specific knowledge. The sigils they use even more so.
@lucifargundam all religious texts tend to have some level of encoded mystery.. the gematria embedded in the bible is pretty impressive in its own right.
