an art of realization
A glimpse of reality and expression of, as a whole, isn’t exactly like an interpretation of a type of reality as one would understand in the arts. In the deep meditative practices of a mind, there is no distinction of the abstract against the real through interpretation filtering (sense, mental-acuity, higher-thought, etc.) as you would in the practice of observing an art piece.
In a very rudimentary way, it can be described as if you were a fish in the water (I use fish here as humans intuit a superior mind over a fish) swimming along, never really knowing or understanding that it’s in a thing human language calls water (in English, anyway). In this way, it’s all things experienced as reality and not just the water bit. It’s not a thing you can grasp, but all things you can and cannot grasp, including all the mechanics of the action, grasping. No individual resides there and there is no there-there of which to go and find. The act of seeking this is the actual idealized separation from it and moves these glimpses further from view, so to speak.
I realize this sounds a lot like nothing-ness, however that nothing-ness is also included in this.
I’m going to bestow to you the very real experience of these “glimpses” these shimmers that other go hand-in-hand with realization, with epiphany, with enlightenment, with the god-moment, etc.
As Science
When Einstein noticed that the clock he saw wasn’t actually in “real time” at the time he viewed it from a distance in contrast to the clock viewed up-close, that was/is that shimmer, that glimpse, that epiphany. So drawn to these realizations the mind can be, it’s a type of euphoria, a seeking of knowing and why science can be so enthralling to some.
As Faith
When your average person sits in prayer and senses that close to god moment, either alone or through a place worship, that realization, that unity with a divine. As above, so below.
As drug induced disassociation
The high where the real stuff falls away from the unreal stuff, where there isn’t a user, using, just raw experience. Also how/why many creatives are users of mind altering drugs which can induce that euphoria, that mental place where creation just flows, good or bad, as interpreted at any given moment.
You should understand that these moments are actually the baseline of being, are the fish that comes to realize they are in fact (always in water), not as a form or type of just living, as a form of being. As above, so below.
