“I want to think about trees. Trees have a curious relationship to the subject of the present moment. There are many created things in the universe that outlive us, that outlive the sun, even, but I can’t think about them. I live with trees. There are creatures under our feet, creatures that live over our heads, but trees live quite convincingly in the same filament of air we inhabit, and in addition, they extend impressively in both directions, up and down, shearing rock and fanning air, doing their real business just out of reach.”

“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.”
