>I posted this on /x/ too but I figured the input from fellow mathematicians, physicists and psychologists (yes, they too) might be helpful

Most esoteric texts (I'm looking at you, GD) hide their lack of understanding in subjective metaphors in the hopes we come up with meaning, the author could be talking out of his ass yet we could still be able to claim his work is a masterpiece due to our made up understanding of his writings.
Every bit of information we know about the material world is derived from a combination of intuition, experience and reason, it would be nice that there was a way to apply a version of these to our understanding of what is beyond the brain, the place where the mind/soul/essence resides well enough that there could be a mathematical description of what this hidden world looks like. Math has become increasingly well equiped to deal with abstraction that is far beyond what we can touch, so much so that we are able tocome up with useful theorems for imaginary places which lack concepts such as time, distance or shape. We are, against all odds, still able to come up with rich descriptions of how objects embedded in these extreme environments interact with each other but how do we become able to distinguish between that which is, that which is not, and that which is circumstantial when trying to develop a complete description of the mindspace? How can I trust myself to be able to come to the right conclusions when I reach into the back of my mind while meditating in an effort to figure out what this new place made out of? Intuition alone might often lead to lies, experience here seems to become twisted.

Are there any books that find a solution to this problem? How do I know the rules this place has when I am not able to use my senses in order to prod it? How am I to understand what is beyond what my mind defines if whenever I let go I feel my sense of self disolving like a drop of food coloring in a boundless glass of water?
