23 September. This story, “The Judgment,” I wrote at one sitting during the night of the 22nd-23rd, from ten o’clock at night to six o’clock in the morning. I was hardly able to pull my legs out from under the desk, they had got so stiff from sitting. The fearful strain and joy, how the story developed before me, as if I were advancing over water. Several times during this night I heaved my own weight on my back. How everything can be said, how for everything, for the strangest fancies, there waits a great fire in which they perish and rise up again. How it turned blue outside the window. A wagon rolled by. Two men walked across the bridge. At two I looked at the clock for the last time. As the maid walked through the anteroom for the first time I wrote the last sentence. Turning out the light and the light of day. The slight pains around my heart. The weariness that disappeared in the middle of the night. The trembling entrance into my sisters’ room. Reading aloud. Before that, stretching in the presence of the maid and saying, “I’ve been writing until now.” The appearance of the undisturbed bed, as though it had just been brought in. The conviction verified that with my novel-writing I am in the shameful lowlands of writing. Only in this way can writing be done, only with such coherence, with such a complete opening out of the body and the soul. Morning in bed. The always clear eyes.
