Here is a Japanese Haiku I read long time back in a book "Glimpses of my golden childhood" - by Osho. I do not remember who the poet is.
Ancient Pond
Frog Jumps In
Plop!
The poet is saying there is an ancient pond - meaning a pond that hasn't changed much for years decades and centuries. A frog comes along, jumps in the water. That makes a sound, a splash. And that't it. It's just a splash. Nothing more nothing less. The pond remains the same.
One can say that the world is that pond. We along with all our aspirations, desires, achievements and failures are like that frog. We jump in and make a splash. But the pond doesn't change.
This is not to say that we shouldn't jump in .... however the perspective helps control our emotions.
p.s. - There is a similar poem by Adi Shankaracharya called "Tat: Kim". In case some may have already read it.
