Nothing is lasting but change; nothing perpetual but death.
All that is solid melts into air. All fixed, fast-frozen relations, with their train of ancient and venerable prejudices and opinions, are swept away, all new-formed ones become antiquated before they can ossify.
Everything proceeds from everything else and everything becomes everything, and everything can be turned into everything else.
Nothing remains the same from one moment to the next, you can't step into the same river twice. Life--evolution--the whole universe of space/time, matter/energy--existence itself--is essentially change.
Observe always that everything is the result of a change, and get used to thinking that there is nothing Nature loves so well as to change existing forms and to make new ones like them.
Everything has changed and nothing is changed.
If things were not impermanent, life would not be possible.
Change alone is eternal, perpetual, immortal.
See Heraclitus {436440} for the ancient Greek exposition of this idea.
Everything changes and nothing stands still.
Nothing endures but change.
The only certainty is uncertainty
Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the Universe loves nothing so much as to change the things which are, and to make new things like them.
everything changes, nothing perishes
The self is only a threshold, a door, a becoming between two multiplicities
Nothing is, everything is becoming.
You can't halt time.
All things are subject to decay and change.
Everything is going to change.
Trend is not destiny.
We're very reluctant to change, even though we know that all things change, and especially our relationships are just determined to change.
Changing, everything is changing.
Five hundred years before Christ was born, the Greek philosopher Heraclitus told his students that "everything changes except the law of change". He said: "You cannot step in the same river twice." The river changes every second; and so does the man who stepped in it. Life is a ceaseless change. The only certainty is today. Why mar the beauty of living today by trying to solve the problems of a future that is shrouded in ceaseless change and uncertainty-a future that no one can possibly foretell?
Nothing is permanent. The only thing any of us have in common is the inevitable.
Everything can change at any moment, suddenly and forever.
That nothing is static or fixed, that all is fleeting and impermanent, is the first mark of existence. It is the ordinary state of affairs. Everything is in process. Everything - every tree, every blade of grass, all the animals, insects, human beings, buildings, the animate and the inanimate - is always changing, moment to moment.
