Xerxes, I read, ‘halted his unwieldy army for days that he might contemplate to his satisfaction’ the beauty of a single sycamore. You are Xerxes in Persia. Your army spreads on a vast and arid peneplain…you call to you all your sad captains, and give the order to halt. You have seen the tree with the lights in it, haven’t you? You must have. Xerxes buffeted on a plain, ambition drained in a puff. Your men are bewildered…there is nothing to catch the eye in this flatness, nothing but a hollow, hammering sky, a waste of sedge in the lee of windblown rocks, a meager ribbon of scrub willow tracing a slumbering watercourse…and that sycamore. You saw it; you will stand rapt and mute, exalted, remembering or not remembering over a period of days to shade your head with your robe. “He had its form wrought upon a medal of gold to help him remember it the rest of his life.” We all ought to have a goldsmith following us around. But it goes without saying, doesn’t it, Xerxes, that no gold medal worn around your neck will bring back the glad hour, keep those lights kindled so long as you live, forever present? Pascal saw it; he grabbed pen and paper and scrawled the one word, and wore it sewn in his shirt the rest of his life. I don’t know what Pascal saw. I saw a cedar. Xerxes saw a sycamore.

Shadow is the blue patch where the light doesn’t hit. It is mystery itself, and mystery is the ancients’ ultima Thule, the modern explorer’s Point of Relative Inaccessibility, that boreal point most distant from all known lands. There the twin oceans of beauty and horror meet. The great glaciers are calving. Ice that sifted to earth as snow in the time of Christ shears from the pack with a roar and crumbles to water. It could be that our instruments have not looked deeply enough. The RNA deep in the mantis’s jaw is a beautiful ribbon. Did the crawling Polyphemus moth have in its watery heart one cell, and in that cell one special molecule, and that molecule one hydrogen atom, and round that atom’s nucleus one wild, distant electron that split showed a forest, swaying?

Today is the winter solstice. The planet tilts just so to its star, lists and holds circling in a fixed tension between veering and longing, and spins helpless, exalted, in and out of that fleet blazing touch. Last night Orion vaulted and spread all over the sky, pagan and lunatic, his shoulder and knee on fire, his sword three suns at the ready-for what? I won’t see this year again, not again so innocent; and longing wrapped round my throat like a scarf. “For the Heavenly Father desires that we should see,” says Ruysbroeck, “and that is why He is ever saying to our inmost spirit one deep unfathomable word and nothing else.” But what is the word? Is this mystery or coyness? A cast-iron bell hung from the arch of my rib cage; when I stirred, it rang, or it tolled, a long syllable pulsing ripples up my lungs and down the gritty sap inside my bones, and I couldn’t make it out; I felt the voiced vowel like a sigh or a note but I couldn’t catch the consonant that shaped it into sense.

Those people who shoot endless time-lapse films of unfurling roses and tulips have the wrong idea. They should train their cameras instead on the melting of pack ice, the green filling of ponds, the tidal swings…They should film the glaciers of Greenland, some of which creak along at such a fast clip that even the dogs bark at them. They should film the invasion of the southernmost Canadian tundra by the northernmost spruce-fir forest, which is happening right now at the rate of a mile every 10 years. When the last ice sheet receded from the North American continent, the earth rebounded 10 feet. Wouldn’t that have been a sight to see?

I am sitting here, you are sitting there. Say even that you are sitting across the kitchen table from me right now. Our eyes meet; a consciousness snaps back and forth. What we know, at least for starters, is: here we- so incontrovertibly- are. This is our life, these are our lighted seasons, and then we die. In the meantime, in between time, we can see. The scales are fallen from our eyes, the cataracts are cut away, and we can work at making sense of the color-patches we see in an effort to discover where we so incontrovertibly are. I am as passionately interested in where I am as is a lone sailor sans sextant in a ketch on an open ocean. I have at the moment a situation which allows me to devote considerable hunks of time to seeing what I can see, and trying to piece it together. I’ve learned the name of some color-patches, but not the meanings. I’ve read books; I’ve gathered statistics feverishly: the average temperature of our planet is 57 degrees F…The average size of all living animals, including man, is almost that of a housefly. The earth is mostly granite, which is mostly oxygen…In these Appalachians we have found a coal bed with 120 seams, meaning 120 forests that just happened to fall into water…I would like to see it all, to understand it, but I must start somewhere, so I try to deal with the giant water bug in Tinker Creek and the flight of three hundred redwings from an Osage orange and let those who dare worry about the birthrate and population explosion among solar systems. So I think about the valley. And it occurs to me more and more that everything I have seen is wholly gratuitous. The giant water bug’s predations, the frog’s croak, the tree with the lights in it are not in any real sense necessary per se to the world or its creator. Nor am I. The creation in the first place, being itself, is the only necessity for which I would die, and I shall. The point about that being, as I know it here and see it, is that as I think about it, it accumulates in my mind as an extravagance of minutiae. The sheer fringe and network of detail assumes primary importance. That there are so many details seems to be the most important and visible fact about creation. If you can’t see the forest for the trees, then look at the trees; when you’ve looked at enough trees, you’ve seen a forest, you’ve got it. If the world is gratuitous, then the fringe of a goldfish’s fin is a million times more so. The first question- the one crucial one- of the creation of the universe and the existence of something as a sign and an affront to nothing is a blank one…The old Kabbalistic phrase is “the Mystery of the Splintering of the Vessels.” The words refer to the shrinking or imprisonment of essences within the various husk-covered forms of emanation or time. The Vessels splintered and solar systems spun; ciliated rotifers whirled in still water, and newts laid tracks in the silt-bottomed creek. Not only did the Vessels splinter; they splintered exceeding fine. Intricacy then is the subject, the intricacy of the created world.

Our life is a faint tracing on the surface of mystery. The surface of mystery is not smooth, any more than the planet is smooth; not even a single hydrogen atom is smooth, let alone a pine. Nor does it fit together; not even the chlorophyll and hemoglobin molecules are a perfect match, for, even after the atom of iron replaces the magnesium, long streamers of disparate atoms trail disjointedly from the rims of the molecule’s loops. Freedom cuts both ways. Mystery itself is as fringed and intricate at the shape of the air at times. Forays into mystery cut bays and fine fjords, but the forested mainland itself is implacable both in its bulk and in its most filigreed fringe of detail.

I have often noticed that these things, which obsess me, neither bother nor impress other people even slightly. I am horribly apt to approach some innocent at a gathering, and like the ancient mariner, fix him with a wild, glitt’ring eye and say, “Do you know that in the head of the caterpillar of the ordinary goat moth there are two hundred twenty-eight separate muscles?” The poor wretch flees. I am not making chatter; I mean to change his life.

It looked as though the leaves of the autumn forest had taken flight, and were pouring down the valley like a waterfall, like a tidal wave, all the leaves of the hardwoods from here to Hudson’s Bay. It was as if the season’s colors were draining away like lifeblood, as if the year were molting and shedding. The year was rolling down, and a vital curve had been reached, the tilt that gives way to headlong rush. And when the monarch butterflies had passed and were gone, the skies were vacant, the air poised. The dark night into which the year was plunging was not a sleep but an awakening, a new and necessary austerity, the sparer climate for which I longed. The shed trees were brittle and still, the creek light and cold, and my spirit holding its breath.

And under the cicadas, deeper down that the longest taproot, between and beneath the rounded black rocks and slanting slabs of sandstone in the earth, ground water is creeping. Ground water seeps and slides, across and down, across and down, leaking from here to there, minutely at a rate of a mile a year. What a tug of waters goes on! There are flings and pulls in every direction at every moment. The world is a wild wrestle under the grass; earth shall be moved. What else is going on right this minute while ground water creeps under my feet? The galaxy is careening in a slow, muffled widening. If a million solar systems are born every hour, then surely hundreds burst into being as I shift my weight to the other elbow. The sun’s surface is now exploding; other stars implode and vanish, heavy and black, out of sight. Meteorites are arcing to earth invisibly all day long. On the planet, the winds are blowing: the polar easterlies, the westerlies, the northeast and southeast trades. Somewhere, someone under full sail is becalmed, in the horse latitudes, in the doldrums; in the northland, a trapper is maddened, crazed, by the eerie scent of the chinook, the sweater, a wind that can melt two feet of snow in a day. The pampero blows, and the tramontane, and the Boro, sirocco, levanter, mistral. Lick a finger; feel the now. Spring is seeping north, towards me and away from me, at sixteen miles a day. Along estuary banks of tidal rivers all over the world, snails in black clusters like currants are gliding up and down the stems of reed and sedge, migrating every moment with the dip and swing of tides. Behind me, Tinker Mountain is eroding one thousandth of an inch a year. The sharks I saw are roving up and down the coast. If the sharks cease roving, if they still their twist and rest for a moment, they die. They need new water pushed into their gills; they need dance. Somewhere east of me, on another continent, it is sunset, and starlings in breathtaking bands are winding high in the sky to their evening roost. The mantis egg cases are tied to the mock-orange hedge; within each case, within each egg, cells elongate, narrow, and split; cells bubble and curve inward, align, harden or hollow or stretch. And where are you now?

In the forty minutes I watched the muskrat, he never saw me, smelled me, or heard me at all. When he was in full view of course I never moved except to breathe. My eyes would move, too, following his, but he never noticed. Only once, when he was feeding from the opposite bank about eight feet away did he suddenly rise upright, all alert- and then he immediately resumed foraging. But he never knew I was there.I never knew I was there, either. For that forty minutes last night I was as purely sensitive and mute as a photographic plate; I received impressions, but I did not print out captions. My own self-awareness had disappeared; it seems now almost as though, had I been wired to electrodes, my EEG would have been flat. I have done this sort of thing so often that I have lost self-consciousness about moving slowly and halting suddenly. And I have often noticed that even a few minutes of this self-forgetfulness is tremendously invigorating. I wonder if we do not waste most of our energy just by spending every waking minute saying hello to ourselves. Martin Buber quotes an old Hasid master who said, “When you walk across the field with your mind pure and holy, then from all the stones, and all growing things, and all animals, the sparks of their souls come out and cling to you, and then they are purified and become a holy fire in you.
