"An Eskimo shaman said, "Life’s greatest danger lies in the fact that man’s food consists entirely of souls"." - Annie Dillard

When her doctor took her bandages off and led her into the garden, the girl who was no longer blind saw “the tree with the lights in it.” It was for this tree I searched through the peach orchards of summer, in the forests of fall and down winter and spring for years. Then one day I was walking along Tinker creek and thinking of nothing at all and I saw the tree with the lights in it. I saw the backyard cedar where the mourning doves roost charged and transfigured, each cell buzzing with flame. I stood on the grass with the lights in it, grass that was wholly fire, utterly focused and utterly dreamed. It was less like seeing that like being for the first time see, knocked breathless by a powerful glance. The flood of fire abated, but I’m still spending the power. Gradually the lights went out in the cedar, the colors died, the cells un-flamed and disappeared. I was still ringing. I had been my whole life a bell and never knew it until at that moment I was lifted and struck. I have since only very rarely seen the tree with the lights in it. The vision comes and goes, mostly goes, but I live for it, for the moment the mountains open and a new light roars in spate through the crack, and the mountains slam.

Chloroplasts bear chlorophyll; they give the green world its color, and they carry out the business of photosynthesis. Around the inside perimeter of each gigantic cell trailed a continuous loop of these bright green dots. They spun . . . they pulsed, pressed, and thronged . . . they shone, they swarmed in ever-shifting files around and around the edge of the cell; they wandered, they charged, they milled, raced . . . they flowed and trooped greenly . . . All the green in the planted world consists of these whole, rounded chloroplasts . . . If you analyze a molecule of chlorophyll itself, what you get is one hundred thirty-six atoms of hydrogen, carbon, oxygen, and nitrogen arranged in an exact and complex relationship around a central ring. At the ring’s center is a single atom of magnesium. Now: If you remove the atom of magnesium and in its place put an atom of iron, you get a molecule of hemoglobin. The iron atom combines with all the other atoms to make red blood, the streaming red dots in the goldfish’s tail.

"You can, in short, lead the life of the mind, which is, despite some appalling frustrations, the happiest life on earth. And one day, in the thick of this, approaching some partial vision, you will (I swear) find yourself on the receiving end of - of all things - an "idea for a story," and you will, God save you, start thinking about writing some fiction of your own. Then you will understand, in what I fancy might be a blinding flash, that all this passionate thinking is what fiction is about, that all those other fiction writers started as you did, and are laborers in the same vineyard."
