Then one day walking round Tavistock Square I made up, as I sometimes make up my books, To the Lighthouse; in a great, apparently involuntary, rush. One thing burst into another. Blowing bubbles out of a pipe gives the feeling of the rapid crowd of ideas and scenes which blew out of my mind, so that my lips seemed syllabling of their own accord as I walked. What blew the bubbles? Why then? I have no notion. But I wrote the book very quickly; and when it was written, I ceased to be obsessed by my mother. I no longer hear her voice; I do not see her.
Sketch of the Past, Virginia Woolf
