Short of that, what does anyone actually HAVE? Not much, except for a fairly well-functioning body/brain system (at least until it slips over that ever-approaching edge of doom into a highly predictable - and when it starts occurring - accelerating decrepitude in all areas of their existence), a few scattered memories of the past and very recent present, and a lot of talk, talk, talk about nothing at all.
Really Mr. or Ms. Human Example of the highest potential this planet (apparently) has spawned in the last several millennia, is THAT all there is?That is the Question to which there is no Known Answer - and thus is called, "The Unnameable Truth". So what is human life, that lasts but a few eyeblinks, with a little pain and pleasure thrown in for good measure, and the same ignorance at the end, as there was at the beginning?
Human life is Potential; unfulfilled, unrealized, only dreamt about and aspired to, without one ever being fully able to give adequate voice to any of it. So, realizing this, a few humans have moved whole bodily, whole heartedly and whole mindfully into the Arts - the fine arts, and the practical arts. If lucky, and persistent, some reach a level of satisfaction and success that could be called "An Answer" of sorts, or "The Truth" of a kind. But, unfortunately for most humans today - being fully embedded in the electronic/digital/information age - they can never attain these results due to the primary reason, that they are now completely distracted, confused and confounded all day long, and for most of the night for their entire lives, and the secondary reason, that they actually prefer distraction, confusion and confoundedness, so they pursue drugs, intoxicants, and addictions of all kinds so as to avoid these ideas entirely. They simply can not get a "leg up", because Life - operating through everyone - keeps dragging them down, into mindless entertainment, and pointless information, none of which leads them to where they WANT to go... to the heights of their ASPIRATIONS.
It is thus, NOT the point of this thing - a kind of art - to reveal precisely WHAT IS "The Unnameable Truth", as that would be ridiculous, but to start focusing on the reasons we can not know it, can not even begin to approach it... but NOT because our fairly well-functioning body/brain system is incapable - because it certainly IS capable - BUT because it has not been prepared for the SHOCK WAVES that would ensue were we to eventually GET a "leg up" and start the Walk of a Lifetime.
