The flow of the river is ceaseless and its water
is never the same. The bubbles that float in the pools, now vanishing,
now forming, are not of long duration; so in the world are man and
his dwellings . (People) die in the morning, they are born
in the evening, like foam on the water."
- Kamo Chomei (1153-1216), Hojo-ki (An account of my hut), 1212
