Famous fragment B12 of Heraclitus has been translated has follows by Professor Jonathan Barnes, an international authority in Ancient philosophy:

On those who enter the same rivers, ever different water flows.

This of course can be understood as another way of saying that one cannot bathe in the same river twice. Because the river is changing all the time. But this translation is remarkable because it suggests more than the idea of universal change.

On those who enter the same rivers, ever different water flows.

This can also mean the following: if one is persistent, visionary, and passionate enough to stick to the very same belief without changing, this courage of holding on what you believe will produce multiple fruits. The water of Difference will flow upon you if you persist in entering the same river. Repetition will produce a state of exception.
