"If I am reading something in another language, say Eliot’s Four Quartets, I spend the first three months reading a section such as “East Coker” over and over again in English until I have it memorized. Then I find a good translation in Japanese and memorize that. Then I go back and forth between the two—the original in English and the Japanese translation—until I feel I am in a spiral that consists of the English text, the Japanese text, and myself. From there Eliot emerges."
