‘(Surely a person is able to sample the experience of eternity without having to read fiction? I found just now a passage that I copied more than thirty years ago from the translated writings of Alfred Jarry: “It is fine to live two different moments of time as one: that alone allows one authentically to live a single moment of eternity, indeed all eternity since it has no moments.”)
From Gerald Murnane’s A Million Windows, p. 17
Time's Flow Stemmed 
What a pleasant coincidence: I’ve just finished reading this book. Murnane considers it as his best.
As do others that know Murnane’s work much better than me.
