At Seventy-third Street I turn off Lexington and head for the Whitney, wanting a last look at a visiting collection. As I approach the museum some German Expressionist drawings in a gallery window catch my eye. I walk through the door, turn to the wall nearest me, and come face to face with two large Nolde watercolors, the famous flowers. I’ve looked often at Nolde’s flowers, but now it’s as though I am seeing them for the first time: that hot lush diffusion of his outlined, I suddenly realize, in intent. I see the burning quality of Nolde’s intention, the serious patience with which the flowers absorb him, the clear, stubborn concentration of the artist on his subject. I see it. And I think, It’s the concentration that gives the work its power. The space inside me enlarges. That rectangle of light and air inside, where thought clarifies and language grows and response is made intelligent, that famous space surrounded by loneliness, anxiety, self-pity, it opens wide as I look at Nolde’s flowers…

That space. It begins in the middle of my forehead and ends in the middle of my groin. It is, variously, as wide as my body, as narrow as a slit in a fortress wall. On days when thought flows freely or better yet clarifies with effort, it expands gloriously. On days when anxiety and self-pity crowd in, it shrinks, how fast it shrinks! When the space is wide and I occupy it fully, I taste the air, feel the light. I breathe evenly and slowly. I am peaceful and excited, beyond influence or threat. Nothing can touch me. I’m safe. I’m free. I’m thinking.
