Flux Poem by Mark Sauer

You can't step twice into the same river,
Nor kiss the same woman ever again;
Changed in the act are taker and giver;
She you love now is not she you loved then;
No more are you him, who stepped, or who kissed.
No speck of that embryo still resides
In your flesh; naught of you now will persist
in your corpse; nor even your soul abides
And is changeless, but like breath in a tempest
Snatched by the blast, is recast in the storm.
The core of you past, the heart of your breast,
Is altered each moment into a new form.
So what is this 'self', sole thing that is yours;
Who is this Watcher, unchanged, who endures?
