Perhaps my answer to 'Ach wie flüchtig, ach wie nichtig.' I find myself fascintated with the advance of time; the 'ever rolling days' to misquote a famous hymn. I imagine the earth marking time, as it forever turns into the light (and into the darkness) and hurtles through space at 100,000 kilometers an hour.
Addendum: listening again, I realize I owe more than a little moral gratitude to Jean Langlais towards the end, and throughout! aml
