Though the river's current never fails, the water passing, moment by moment, is never the same. Where the current pools, bubbles form on the surface, bursting and disappearing as others rise to replace them, none lasting long. In this world, people and their dwelling places are like that, always changing. (ゆく河の流れは絶えずして、しかももとの水にあらず。淀みに浮かぶうたかたは、かつ消えかつ結びて、久しくとどまりたるためしなし。世の中にある人とすみかと、またかくのごとし。 英訳: http://www.washburn.edu/reference/bridge24/Hojoki.htmlより)
