Effulgent Forms

"That inner Self, as the primeval Spirit, Eternal, ever effulgent, full and infinite Bliss, Single, indivisible, whole and living, Shines in everyone as the witnessing awareness. That self in its splendor, shining in the cavity of the heart This self is neither born nor dies, Neither grows nor decays, Nor does it suffer any change. When a pot is broken, the space within it is not, And similarly, when the body dies the Self in it remains eternal."

- Ramana Maharshi (1879 - 1950)

Ryutan's Candle

"Tokusan once called on Ryutan to ask for instruction and stayed until night fell. Ryutan said, 'It is getting late; you had better leave.' At last Tokusan said good-bye, lifted up the door curtain, and went out. Noticing that it was dark, he turned back and said, 'It is dark outside.' Ryutan thereupon lit a candle and handed it to him. Tokusan was about to take it when Ryutan blew it out. At this Tokusan was all of a sudden enlightened. He made a bow. Ryutan asked, 'What realization do you have?' Tokusan replied, 'From now on I will not doubt the sayings of any of the great Zen Masters in the world.'

The next day Ryutan mounted the rostrum and declared, 'Among the monks here there is a fellow whose fangs are like swords, and whose mouth is like a bowl of blood. You may strike him with a stick but he will not turn his head. Some day in the future, he will establish his way on a steep and lofty peak.' 

Tokusan then took out his notes and commentaries on the Diamond Sutra and in front of the monastery hall he held up a burning torch and said, 'Even though one masters various profound philosophies, it is like placing a single strand of hair in the great sky; even if one gains all the essential knowledge in the world, it is like throwing a drop of water into a deep ravine.' Taking up his notes and commentaries, he burned them all. Then he left with gratitude."

- Zen Koan (Gateless Barrier, #28/page 201)

Whirling Light

"Rotating systems often break axisymmetry; were it not so, there would be no hurricanes. There are steadier examples: the skirts of the 'whirling dervish' carry cusped wave patterns which seem to defy gravity and common sense.

...

We consider a rotating, conically symmetric surface made out of a sheet of material that is constrained not to stretch or compress in two dimensions, but is perfectly flexible with respect to bending in the third. The symmetry of the surface permits an additional material flow to be superimposed on the rotation of the surface, leading to Coriolis forces. The equations describing this system yield a three-parameter family of exact solutions, some of which bear a close resemblance to the patterns on a dervish's skirt. We find that the Coriolis terms that arise from the additional flow are crucial for these types of patterns to exist.

...

The results widen our understanding of the dynamics of flexible objects and of pattern formation in rotating systems. They may also shed some light on previously known instabilities of turbine disks and hard disks. Finally, they bring a bit of science into the otherwise nebulous world of the mystic, and address a phenomenon that has been observed with aesthetic pleasure for hundreds of years."

Postscript. The images in the diptych that I took with my iPhone recently (of light reflecting off of cars parked onto the walls of a local garage) reminded me of Rumi's "Whirling Dervishes," about which you can read here and here (in considerably less technical detail than the one you'll find if you follow the link to the physics journal!)

“You are water, whirling water,
Yet still water trapped within,
Come, submerge yourself within us,
We who are the flowing stream.
...
We came whirling out of nothingness,
scattering stars like dust...
The stars made a circle,
and in the middle,
we dance.”

- Rumi (1207 - 1273

Leaves and Paths

"In a forest of a hundred thousand trees,
no two leaves are alike.
And no two journeys along
the same path are alike."

Between Grief and Geometry

"Geometry is a way to organize our models of the world, its shapes and dynamics. But isn’t this all contingent, balanced on a knife’s edge? Could our models have turned out very differently? If the fractal geometry of Mandelbrot had been discovered before the geometry of Euclid, would manufacture be the same? If you think the question is far-fetched, consider the iterated branching of our pulmonary, circulatory, and nervous systems, or the recursive folding of our DNA, or the large surface area and small volume of our lungs and our digestive tract. Evolution has discovered and uses fractal geometry. If people had looked more closely at the geometry of nature, rather than emulating the 'celestial perfection' imposed by the church’s interpretation of the works of Euclid and Aristotle, our constructions could be very different now.

...

Beauty is a bridge between grief and geometry.

...

Beauty and grief are next-door neighbors, or maybe grief is beauty in a dark mirror… To see beauty is to glimpse something deeper; to grieve is to glimpse a loss whose consequences we will not unpack for years, and maybe never. The beauty of geometry likewise involves great emotional weight, irreversibly alters our perceptions, and is transcendent. For we don’t see all of geometry, only a hint, a shadow of something much deeper."

Harmony of Autumnal Colors

"When the eye sees a color it
is immediately excited,
and it is its nature,
spontaneously and of necessity,
at once to produce another,
which with the original colour
comprehends the whole chromatic scale.
A single color excites,
by a specific sensation,
the tendency to universality.
In this resides the fundamental
law of all harmony of colors.
...

Should your glance on mornings lovely

Lift to drink the heaven's blue

Or when sun, vieled by sirocco,

Royal red sinks out of view -

Give to Nature praise and honour.

Blithe of heart and sound of eye,

Knowing for the world of color

Where its broad foundations lie."

- Johann Wolfgang von Goethe (1749 - 1832)

Autumnal Tints

"I am struck by the simplicity of
light in the atmosphere in the autumn,
as if the earth absorbed none,
and out of this profusion of
dazzling light came the
autumnal tints."

- Henry David Thoreau (1817 - 1862)
