Although I appreciate the open venture you pursue insofar as all of this mystical stuff goes, there lacks a certain content for it to signify much to me. You see, to say that we cannot shut ourselves off to the possibility can either imply two different things : that we are looking for it, or that we do not deny it. I feel like, and particularly in this poem, you are of the former category. Let me explain. I've never endorsed thoughts that debase the basic value of the body -- the corporeal clod as some say. You are turning your back to the very process that at times seems to define the universe -- and to posit the existence of much more beyond it is to turn your back even further on this realm we call reality. Why? I like Freud's concept of the "reality principle" as this thing which is the first force to impose itself upon the biological organism and is that against which that very organism strives for the rest of its existence. He called it a biological kind of elasticity; even here, however, I find a precept that enacts my dissatisfaction. Freud has to posit the existence of an initial nirvana, if you will, which explains the whole potential energy and elasticity bit.
Are we really so propelled by pleasure, or what nietzsche calls power, that we cannot overcome it, even in overcoming it? And this escapist dream you have of a mystical departure: is it a sincere want, a genuine interest, or just another selfish pleasure-oriented gambit, a try to overcome reality. Why must reality be overcome, or transformed? Equilibrium isn't any better an attempt than a total upheaval, because it is the equivalent of a wall. The wall of non-communication. The cessation of reality communicative propriety and dominion over man's mind. Your mysticism is much more destructive than you might think. And people often overlook the individual nature of these pathways, and whether personal ambition or greed is to blame is hard to say. How can a monk truly climb to sagacity and leave his peers behind because they "do not understand" or "are not looking for the answer"? I could steal people's money because they "do not understand" or "are not looking to keep it".
But those are just my personal gripes. Sorry I did not relate in the way you may have wished.
