Understand Poem by Christopher Teale

I look upon the fragile existence of our Universe,
Entropy and chaos, emptiness and death
Every atom decaying, whilst I write this very verse
Life failing from existence with every single breath

Should I tremble, should I be afraid?
My soul views it coldly, with no sentiment.
For also mirth and sorrow fade
as time passes and life is spent

Then I look on man and his bold buildings
And laugh at the naivety of our race
So easily fooled by passion and feelings
too readily do we fall into disgrace

And I look upon a flower and I weep
As decay would make it sour to soon
by morning we plant, by noon we reap
Decay and rot, what once was bloom

Even as I look on the stars, they seem eternal
But they die to share their substance for creation
Light to dust, powerful and great! Yet ephemeral
Suddenly, sorrow for terrible loss becomes elation,
in understanding.
