A Theologian, a Poet, and a Mathematician contemplate the mystery of the Creation

The whole meaning of the Universe   is contained in the Koran.

The whole meaning of the Koran, is contained in any Sura thereof.

The whole meaning of any Sura, may be confidently derived, from the deepest meaning, of any individual ayah of the same.

And that (for them that understand), from any one word within.

And  -- that -- from any letter therein.

And …  that  …  from but … the merest (least) [minimal] diacritical

   point thereon …..

-- Received Muslim wisdom

To see a World in a Grain of Sand

And a Heaven in a Wild Flower,

Hold Infinity in the palm of your hand

And Eternity in an hour.

-- Wm. Blake

The period at the end of this sentence  looks, from afar, like a connected, dimension-0 manifold

-- Timothy Gowers, ed., The Princeton Companion to Mathematics (2008), p. 398

[Note to connoisseurs:  Notice that there is actually no period at the end of that sentence …]

The general idea expressed in the first two meditations  was classically denoted by the phrase ex pede Herculem (i.e., given knowledge of proportions, you could 'project' the full statue from the ruin remains of just a foot).

A more startling analogue from mathematics:  the "Reflection Principle" in Set Theory.

For a walk-into-a-bar joke, replete with religious mysticism:

As for theologians, well, they’re well beyond that.
