Everything is in constant flux on this earth. Nothing keeps the same unchanging shape, and our affections, being attached to things outside us, necessarily change and pass away as they do. Always out ahead of us or lagging behind, they recall a past which is gone or anticipate a future which may never come into being; there is nothing solid there for the heart to attach itself to. Thus our earthly joys are almost without exception the creatures of a moment...

Everything on earth is in continuous flux: nothing preserves a constant fixed form, and our affections towards external things pass and change with them... There is nothing solid to which the heart can attach itself. Also, there is scarcely a pleasure here below which does not pass; as for enduring happiness, I doubt that it can be known. In our most vivid joys there is scarcely an instant at which our hearts could truly say: would that this moment might last forever; and how can one call that transient state happy which still leaves our hearts disturbed and empty, which makes us regret something beforehand or still desire something afterwards.

Things of this world are in so constant a flux that nothing remains long in the same state.

Everything flows and nothing abides; everything gives way and nothing stays fixed.

My vessel is launched on the boundless main and my sails are spread to the wind ! In the whole of the world there is nothing that stays unchanged. All is in flux. Any shape that is formed is constantly shifting.
Time itself flows steadily by in perpetual motion. Think of a river: no river can ever arrest its current, nor can the fleeting hour. But as water is forced downstream
by the water behind it and presses no less on the water ahead, so time is in constant flight and pursuit, continually new. The present turns into the past and the future replaces the present; every moment that passes is new and eternally changing.

Nothing persists, said the ancient sages: everything changes, everything flows, everything becomes; consequently, everything remains and everything is connected; by further consequence the entire universe is opposition, balance, equilibrium. There is nothing, neither outside nor inside, apart from that eternal dance; and the rhythm that commands it,

Everything fluctuates on earth; nothing remains in a constant and lasting form, and those affections which are attached to external things necessarily change with their object. We are ever looking forward or backward, ruminating on what is past, and can return no more, or anticipating the future, which may never arrive; there is nothing solid to which the heart can attach, itself, neither have we here below any pleasures that are lasting. Permanent, happiness is, I fear, unknown, and scarcely is there an instant in our most lively enjoyments when the heart can truly say, May this moment last forever!!! How then can such a fugitive state be called happiness, which leaves an uneasy void in the heart, which ever prompts us to regret something that is past, or desire something for the future?

We are ever looking forward or backward, ruminating on what is past, and can return no more, or anticipating the future, which may never arrive; there is nothing solid to which the heart can attach itself, neither have we here below any pleasures that are lasting.

For all bodies are in perpetual flux like rivers, and parts are passing in and out of them continually.

Everything on earth changes - we have no abiding city here - it is the experience of everybody. That it is God’s will that we should part with what is dearest on earth - we ourselves change in many respects, we are not what we once were, we shall not remain what we are now.

There is nothing constant in the universe. All ebb and flow, and every shape that's born, bears in its womb the seeds of change.

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. We don’t have to be mystics or physicists to know this. Yet at the level of personal experience, we resist this basic fact. It means that life isn’t always going to go our way. It means there’s loss as well as gain.

All is flux, nothing stays still

So do flux and reflux — the rhythm of change — alternate and persist in everything under the sky.
