"And then, for one glorious, supreme moment, came "the flash".
Emily called it that, although she felt that the name didn't exactly describe it.
It had always seemed to Emily, ever since she could remember, that she was very, very near to a world of wonderful beauty. Between it and herself hung only a thin curtain; she could never draw the curtain aside - but sometimes, just for a moment, a wind fluttered it and then it was as if she caught a glimpse of the enchanting realm beyond - only a glimpse - and heard a note of unearthly music.
This moment came rarely - went swiftly, leaving her breathless with the inexpressible delightful of it. She could never recall it - never summon it - never pretend it; but the wonder of it stayed with her for days. It never came twice with the same thing. Tonight the dark boughs against that far-off sky had given it. It had come with a high, wild note of wind in the night, with a shadow wave over a ripe field, with a greybird lighting on her window-sill in a storm, with the singing of "Holy, holy, holy" in church, with a glimpse of the kitchen fire when she had come home on a dark autumn night, with the spirit-like blue of ice palms on a twilit pane, with a felicitous new word when she was writing down a description of something. And always when the flash came to her Emily felt that life was a wonderful, mysterious thing of persistent beauty."
