I'm looking for a word.....

[erja]

I'm not sure if one even exists.

... to put across just how crazy life is, how it never stops moving, how everything is temporary, how there's always something good round the corner, how when you think you won't find something good again you always do.

If that makes sense! I can't find a work to sum it all up. Is there even one that comes close?

penguingirl

OP, i don't thnk there is one word to sum all that up really.

Why is this word important OP?

Transient.

Looked up Samsara and think PP newroundhere got it right

Hamster wheel

Rollercoaster?

Chaos theory

I think only German is likely to have one word that sums all of that up.

Sounds like the notion of Karma ?
