When he starts a novel, it works like this. First he writes a sentence. Then he rewrites it again and again, examining each word, making sure of its perfection, finely honing each phrase until it reverberates with the subtle texture of the infinite. Sometimes it takes hours. Sometimes an entire day is devoted to one sentence, which gets marked on and expanded upon in every possible direction until he is satisfied. Then, and only then, does he add a period.
