He looks at houses, chateaus, forests, and thinks about the countless generations who used to see those things and who are gone now; and he understands that everything he is seeing is oblivion; pure oblivion, the oblivion whose absolute state will soon be achieved, the moment he himself is gone. And again I think about the obvious idea (that astoundingly obvious idea) that everything that exists (nation, thought, music) can also not exist.

I always think everything is going to last forever, but nothing ever does. In fact nothing exists longer than an instant except the thing that we hold in memory

I believe in the brief eternity of the rose.

If a beautiful thing were to remain beautiful for all eternity, I'd be glad, but all the same I'd look at it with a colder eye. I'd say to myself: You can look at it any time, it doesn't have to be today.

— Hermann Hesse

If nothing lasts then everything has meaning. If everything dies that means we actually live.

...if we seek the permanence of an object as something existing from its own side, we discover something inexpressible. If we take three sticks and place them together in a certain way, they will all stand up. If each of the sticks could stand under its own power, it would remain standing even if the others were removed, but they cannot. In this way we must understand dependent arising precisely. Another way of thinking about it is to consider clothing. Only when cloth is of the correct color, shape, and so forth is it labeled "clothing." Or think of a clock. Whenever we see a clock, we label it a clock, but if we were to separate the component pieces, then the "clock" would cease to exist, because no basis of imputation would remain. In actuality there was no truly existent clock in the first place—only the causes and conditions fit to be labeled a "clock.

Impermanence and selflessness are not negative aspect of life, but the very foundation on which life is built. Impermanence is the constant transformation of things. Without impermanence, there can be no life. Selflessness is the interdependent nature of all things. Without interdependence, nothing could exist.

— Thich Nhat Hanh

In reality nobody can grasp anything permanently in life. Absolutely nothing. Something's may stay in memory for a while but eventually that too fades away.

It all goes away. Eventually, everything goes away.
