“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.”

“Beauty and grace are performed whether or not we will or sense them. The least we can do is try to be there.”

“There is a muscular energy in sunlight corresponding to the spiritual energy of wind.”

“Buddhism notes that it is always a mistake to think your soul can go it alone.”

“Just think: in all the clean, beautiful reaches of the solar system, our planet alone is a blot; our planet alone has death.”

“As soon as beauty is sought not from religion and love, but for pleasure, it degrades the seeker.”

“The notion of the infinite variety of detail and the multiplicity of forms is a pleasing one; in complexity are the fringes of beauty, and in variety are generosity and exuberance.”

“It is ironic that the one thing that all religions recognize as separating us from our creator, our very self-consciousness, is also the one thing that divides us from our fellow creatures. It was a bitter birthday present from evolution.”

“You can't test courage cautiously.”

“The surest sign of age is loneliness.”

“There must be bands of enthusiasts for everything on earth-fanatics who shared a vocabulary a batch of technical skills and equipment and perhaps a vision of some single slice of the beauty and mystery of things of their complexity fascination and unexpectedness.”
