It was at a concert of lovely old music. After two or three notes of the piano the door was opened of a sudden to the other world. I sped through heaven and saw God at work. I suffered holy pains. I dropped all my defenses and was afraid of nothing in the world. I accepted all things and to all things I gave up my heart. It did not last very long, a quarter of an hour perhaps; but it returned to me in a dream at night, and since, through all the barren days, I caught a glimpse of it now and then.
