Man, the deeper i get into this mysticism subject, the more interesting and intense it becomes.
Originally, i found it really hard to grasp (a lot of the texts were poetry or really superfluous "beautiful" language). I tend to prefer the Anglo/Analytical style of philosophy which is almost scientific in its being straight to the point. I dont really dig the prose you find in the rest of Europe.
That said, actually making through it is way more rewarding because of its challenging nature and prose. A lot of the ideas blow my mind as well. I just wrote a whole essay on apophatic theology, the idea you can only describe God by saying what he isn't. If you say what God is, once you name or catergorise something, you begin to limit it (and God has no limits). God existed before the creation of the universe and categories and differentiation only came about within and after the creation of the universe, these categories or differentiation didn't exist alongside God.
So, all you can really say is "God **is not** short" because that would be to limit him and apply human ideas to him. The only way you can really come to know God according to these guys is to "unknow" everything, erase all ideas of concepts and differentiation of God and accept him as the as a single and unitary substance of no/one quality. That's weird (unknow everything to know things) but it gets even weirder still.
All this shit is really blowing my mind. The religion of the philosophers and mystics is so, so much deeper than the religion in churches or the average person on the street. It's orders of magnitude more interesting and dare i say sensible.
