[Knygathin]

We like to think of ourselves, in the form of human beings, as the top of creation and evolutionary ladder, as enlightened, and perceptive, as morally superior. But our understanding of reality is limited, perverted, and illusionary. For one thing, our anatomical parts are specialized and meagerly developed, fitting into a small earthbound section of reality. And compared to other species, our eyes (we are used to the bent cockeyed picture seen through those particular small lenses), ears, noses, and sensory touches, are inferior, less developed. We perceive only a small and distorted part of reality, far from all sides of reality. And we don't understand so much as we like to think we do. Symbolically we can be said to be sitting inside an "apartment" with walls shielding us all around. We have only recently started to walk upright, which our spines are not even yet anatomically adapted for. Objectively speaking, we are freaks.
Human beings are very very smug and arrogant in their self-positioning. When, instead, we should look humbly upon ourselves as just one among several animal species.

I believe individuals can have glimmerings of more enlightened perception (non-Aristotelian logic, "null-A" to quote A. E. van Vogt), but it rarely lasts.
I also believe evolution can bring Homo sapiens, with time, to something else, of a much higher level of development; but whether that will happen, or not, is dependent on many un-forseeable circumstances of future history. The best we can do, is to strive for it, as maturely as we are able; that is a positive aspect we already possess, in part, for a rough direction.

As to supernatural or spiritual perceptions, I believe those can also be a form of faint glimmering beyond our physical capacity (if not, more often, purely mental illusions and emotional distortions of the senses). But such experiences are so personal, that they cannot really be shared with others. The responses from telling others, will not be meaningful beyond gaping disbelief and blank stares; in other words, deeply unsatisfactory. Such experiences are best left transformed into the arts, where some meaning may be destilled from it.
