The mountain endures. But when after ages it has worn away, it has gone. If a replica arises, it is yet a new mountain.

A colour is eternal. It haunts time like a spirit. It comes and it goes. But where it comes, it is the same colour. It neither survives nor does it live.

What can poor mortals say about clouds?While a description of their huge glowing domes and ridges, shadowy gulfs and canyons, and feather-edged ravines is being tried, they vanish, leaving no visible ruins. Nevertheless, these fleeting sky mountains are as substantial and significant as the more lasting upheavals of granite beneath them. Both alike are built up and die, and in God's calendar difference of duration is nothing. We can only dream about them in wondering, worshiping admiration, happier than we dare tell even to friends who see farthest in sympathy, glad to know that not a crystal or vapor particle of them, hard or sot, is lost; that they sink and vanish only to rise again and again in higher and higher beauty.

Light. Space. Light and space without time, I think, for this is a country with only the slightest traces of human history. In the doctrine of the geologists with their scheme of ages, eons and epochs all is flux, as Heraclitus taught, but from the mortally human point of view the landscape of the Colorado is like a section of eternity- timeless. In all my years in the canyon country I have yet see a rock fall, of its own volition, so to speak, aside from floods. To convince myself of the reality of change and therefore time I will sometimes push a stone over the edge of a cliff and watch it descend and wait- lighting my pipe- for the report of its impact and disintegration to return. Doing my bit to help, of course, aiding natural processes and verifying the hypotheses of geological morphology. But am not entirely convinced.

The things that look fixed in the world, child — mountains, wealth, empires — their permanence is only an illusion. We believe they will last, but that is only because of the brevity of our own lives. From the perspective of God, cities like this come and go like anthills.

We long for permanence but everything in the known universe is transient. That’s a fact but one we fight.

The years pass in their hundreds and their thousands, and what does any man see of life but a few summers, a few winters? We look at mountains and call them eternal, and so they seem... but in the course of time, mountains rise and fall, rivers change their courses, stars fall from the sky, and great cities sink beneath the sea. Even gods die, we think. Everything changes.

Les montagnes bougent, c'est juste qu'elles bougent lentement.

Everything is temporary

You look at these mountains now, and they look so permanent and peaceful, but they're changing all the time and the changes aren't always peaceful. Underneath us, beneath us here right now, there are forces that can tear this whole mountain apart.

All knowledge is transient, linked to the world around it and subject to change as the world changes.

Mountains, a moment’s earth-waves rising and hollowing; the earth too’s an ephemerid; the stars — Short-lived as grass the stars quicken in the nebula and dry in their summer, they spiral
Blind up space, scattered black seeds of a future; nothing lives long, the whole sky’s
Recurrences tick the seconds of the hours of the ages of the gulf before birth, and the gulf
After death is like dated: to labor eighty years in a notch of eternity is nothing too tiresome,
Enormous repose after, enormous repose before, the flash of activity.

Greatness is a transitory experience. It is never consistent.

Of the laws we can deduce from the external world, one stands above all: the Law of Transience. Nothing is intended to last. The trees fall year by year, the mountains tumble, the galaxies burn out like tall tallow candles. Nothing is intended to last — except time. The blanket of the universe wears thin, but time endures. Time is a tower, an endless mine; time is monstrous. Time is the hero. Human and inhuman characters are pinned to time like butterflies to a card; yes, though the wings stay bright, flight is forgotten. Time, like an element which can be solid, liquid or gas, has three states. In the present, it is a flux we cannot seize. In the future, it is a veiling mist. In the past, it has solidified and become glazed; then we call it history. Then it can show us nothing but our own solemn faces; it is a treacherous mirror, reflecting only our limited truths. So much is it a part of man that objectivity is impossible; so neutral is it that it appears hostile.

THINGS HAVE ENDS AND BEGINNINGS” Cloud mountains rise over mountain range. Silence and quietness, sky bright as water, sky bright as lake water. Grace is the instinct for knowing when to stop. And where.
