“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 no Chomei, from Hojoki: Visions of a Torn World (Stone Bridge Press, 1996)
