Fiery Light

"A fiery light, of the greatest flashing brightness, coming out of a cloudless sky, flooded my entire mind and so inflamed my whole heart and my whole breast like a flame — yet it was not blazing but glowing hot, as the sun makes anything on which its rays fall hot. 

...

And I saw as if in the middle of the southern sky an image, beautiful and wonderful in the mystery of God, like a human in form. Her face was of such beauty and radiance that I could more easily look at the sun than at her; and a great circlet of golden color surrounded her head. [...] And this image spoke: ‘I am the supreme and fiery force, who sets all living sparks alight and breathes forth no mortal things, but judges them as they are. Flying around the circling circlet with my upper wings - with my wisdom - I have ordered all things rightly. But I am also the fiery life of the essence of divinity; I flame above the beauty of the fields, and I shine in the waters, and I burn in the sun, the moon, and the stars. With the airy wind I quicken all things with some invisible life that sustains them all. For the air lives in viridity [i.e., greenness] and in the flowers, the waters flow as if alive, and the sun lives within its own light.

...

The light that I see thus is not spatial, but it is far, far brighter than a cloud that carries the sun. I can measure neither height, nor length, nor breadth in it; and I call it the 'reflection of the living Light.'"

- Hildegard of Bingen (1098 - 1179)

Platonic Forms

"And now look again, and see what will naturally follow if the prisoners are released and disabused of their error. At first, when any of them is liberated and compelled suddenly to stand up and turn his neck round and walk and look towards the light, he will suffer sharp pains; the glare will distress him, and he will be unable to see the realities of which in his former state he had seen the shadows; and then conceive some one saying to him, that what he saw before was an illusion, but that now, when he is approaching nearer to being and his eye is turned towards more real existence, he has a clearer vision. [...] Will he not fancy that the shadows which he formerly saw are truer than the objects which are now shown to him? [...] He will require to grow accustomed to the sight of the upper world. And first he will see the shadows best, next the reflections of men and other objects in the water, and then the objects themselves; then he will gaze upon the light of the moon and the stars and the spangled heaven; and he will see the sky and the stars by night better than the sun or the light of the sun by day. [...] Last of all he will be able to see the sun, and not mere reflections of him in the water, but he will see him in his own proper place, and not in another; and he will contemplate him as he is. [...] This entire allegory you may now append, dear Glaucon, to the previous argument; the prison-house is the world of sight, the light of the fire is the sun, and you will not misapprehend me if you interpret the journey upwards to be the ascent of the soul into the intellectual world according to my poor belief, which, at your desire, I have expressed - whether rightly or wrongly God knows. But, whether true or false, my opinion is that in the world of knowledge the idea of good appears last of all, and is seen only with an effort; and, when seen, is also inferred to be the universal author of all things beautiful and right, parent of light and of the lord of light in this visible world, and the immediate source of reason and truth in the intellectual; and that this is the power upon which he who would act rationally, either in public or private life, must have his eye fixed."

- Plato (c.424 - 348 BC)
"The Allegory of the Cave" (Republic, Book Seven) 

Seed Unfolding

"The One, perfect in seeking nothing, possessing nothing and needing nothing, overflows and creates a new reality by its superabundance. [...] The process is like the unfolding of a seed, moving from simple origin to termination in the world of sense, the prior always remaining in its place, while begetting its successor from a store of indescribable power - power that must not halt within the higher realm [...] but continue to expand until the universe of things reaches the limit of its possibility, lavishing its vast resources on all its creatures, intolerant that any one should have no share in it. Nothing is debarred from participation in the Good, to the extent of its receptivity. "

- Plotinus (c. 204/5 – 270 CE)
The Enneads

Luminous Forms

"Architecture is the masterly, correct and magnificent play of masses brought together in light. Our eyes are made to see forms in light; light and shade reveal these forms; cubes, cones, spheres, cylinders or pyramids are the great primary forms which light reveals to advantage; the image of these is distinct and tangible within us without ambiguity. It is for this reason that these are beautiful forms, the most beautiful forms. Everybody is agreed to that, the child, the savage and the metaphysician."

- Le Corbusier (1887 - 1965)

Spiritual Facts

"Particular natural facts are symbols of particular spiritual facts. [...] Nature is the symbol of spirit. [...] Every natural fact is a symbol of some spiritual fact. Every appearance in nature corresponds to some state of the mind, and that state of the mind can only be described by presenting that natural appearance as its picture. [...] By degrees we may come to know the primitive sense of the permanent objects of nature, so that the world shall be to us an open book, and every form significant of its hidden life and final cause."

- Ralph Waldo Emerson (1803 - 1882)
Nature

Rhythmic Measures

"The same stream of life that runs
through my veins night and day runs through
the world and dances in rhythmic measures.
It is the same life that shoots in joy
through the dust of the earth in numberless blades of grass
and breaks into tumultuous waves of leaves and flowers.
It is the same life that is rocked in the ocean-cradle
of birth and of death, in ebb and in flow.
I feel my limbs are made glorious by the touch of this world
of life. And my pride is from the life-throb of ages
dancing in my blood this moment."

- Rabindranath Tagore (1861 - 1941)

Possible Worlds

 "As there are an infinity of possible worlds,
there are also an infinity of laws,
certain ones appropriate to one; others,
to another, and each possible individual
of any world involves in its concept
the laws of its world."

- G.W. Leibniz (1646 - 1716)

Spirit World

"...As with the man on the mountaintop, extraordinary imaginings and singular sensations arise that seem to grow out beyond all bearing. But it is necessary for us to experience that too. We must assume our existence as broadly as we in any way can; everything, even the unheard-of, must be possible in it. That is at bottom the only courage that is demanded of us: to have courage for the most strange, the most singular and the most inexplicable that we may encounter. That mankind has in this sense been cowardly has done life endless harm; the experiences that are called 'visions,' the whole so-called 'spirit-world,' death, all those things that are so closely akin to us, have by daily parrying been so crowded out of life that the senses with which we could have grasped them are atrophied. To say nothing of God."

- Rainer Maria Rilke (1875 - 1926)
Letters to a Young Poet (Letter 8)

Fleeting Vortices

"[Physicists and naturalists cannot] look down from a great height upon a world which their consciousness could penetrate without being submitted to it or changing it. [...] a more complete study of the movements of the world will oblige us ... to discover that if things hold and hold together, it is only by reason of complexity, from above.

...

Hence we find our minds instinctively tending to represent energy as a kind of homogeneous, primordial flux in which all that has shape in the world is but a series of fleeting 'vortices'. [...] each new being has and must have a cosmic embryogenesis ...

...

Science, philosophy and religion are bound to converge ...
but without merging, and without ceasing, to the very end,
to assail the real from different angles
and on different planes."

- Teilhard De Chardin (1881- 1955)
The Phenomenon of Man

More is Diferent

"At each level of complexity entirely new properties appear, and the understanding of the new behaviors requires research which I think is as fundamental in its nature as any other. That is, it seems to me that one may array the sciences roughly linearly in a hierarchy, according to the idea: The elementary entities of science X obey the laws of science Y. But this does not at all imply that science X is 'just' science Y. At each stage entirely new laws, concepts, and generalizations are necessary, requiring inspiration and creativity to just as great a degree as in the previous one."
