Fragment 91

[For, according to Heraclitus, it is not possible to step twice into the same river, nor is it possible to touch a mortal substance twice in so far as its state is concerned. But, thanks to the swiftness and speed of change,] it scatters and brings together again, [(or, rather, it brings together and lets go neither again nor later, but simultaneously)] it forms and dissolves, and it approaches and departs (Robinson).
