Quote of the day by Heraclitus: 'No man ever steps in the same river twice, for it's not the same river and he's not the same man' and a lesson on how change is the only constant

Heraclitus, an ancient Greek philosopher from Ephesus, stated that reality is a ceaseless flow, with fire symbolizing transformation.

His river metaphor asserts that stability is an illusion, as both the river and the person change continuously.

The phrase panta rhei ('everything flows') is associated with his philosophy.

The quote captures the idea that change is the only constant in existence.
