Manifestations of the 3-D Grid — Beyond Muryoju-do

A recurring motif — corridors running parallel and intersecting across all three axes. A first-person perspective wandering long, wide and deep in a anti-maze semblant, yet abstruse regarding purpose and direction.

One actualisation of this theme exhibited itself in the vicinity west of Tech. On a bachelor’s last night of revelry a double-decker was employed to traverse the town's hot spots. (It is unfortunate that a bottle of Old Grand-Dad was casualty to a sharp turn, as it had tumbled down the aisle and stairwell [90°], shattering all too close to the hapless driver.)
  After ritual humiliations at the Cheetah III, the crew retreated to the lone penthouse atop the old White Provision building. Merriment for the others ensued, but further investigation of the deserted structure found a labyrinth of hallways, dim stretches of concrete reminiscent of the old bunker that became Seaside Pungeonary.

A second exposition of the theme occurred near Kiyomizu-dera. A jaunt from the temple downhill through the valley of obelisks, one finds a windowless trapezoidal structure. Inside was a latticework of passages, alcove shrines in a haze of incense, and the droning sutra of meditations humming from within. (As it turns out, this building was a Buddhist columbarium known as the First Hall of Immeasurable Life.)

Two real-life instances that have triggered the memory of a frequent but oft-forgotten dream fragment. Surely, Freud, Jung and dream dictionary dilettantes would have a field day with armchair analyses.
  But let us look at the most obvious thing in common threading between dream and reality: the ever-present spirit of exploration, delineated upon the most basic schema of the conscious mind’s orientation — deportment of the physical in the three dimensions. The lasting impressions of geometric harmony in the columbarium raise considerations of “rebirth,” the Land of Bliss, and other levels in the Buddhist cosmology, in the context of the three dimensions we grasp with our senses and in our dreams.

Paradigm Para-digression:

Residents of Flatland could not perceive Spaceland, and those visiting from Spaceland would only appear as fleeting shapes, sectionals of solids passing through the plane.
  What lay beyond Spaceland? The Square posited the realm of Thoughtland, though the idea was found preposterous by the Sphere.

Johnny Gutts offers us a pithy pseudo-koan:
“As Prometheus gave us the flame, the sun grazed Icarus’ wings with the same. From Dharmakāya what can we claim?”

To the layman, a question echoes throughout those halls still:
“What is the geometric balance between curiosity, enlightenment and hubris?”
