This is a small excerpt of the actual poem. It is entitled The Curious Case of the Blossoming Clouds and can relate not only to youth, but to everyone and everything that grows because no end is reached until the ultimate end itself.
At first, atoms existed
In that time before time
When nothing was here.
With time, blossoms grew
From the atoms that had existed,
And yet time did not grow
And neither did the earth,
Because just like everything that blossoms,
An end is reached.
