This poem comes from Autumn Leaves:

Beautiful silver kings from ocean depths,

Trying to fulfill your dreams,

Battling white water currents

Over obstacles in the streams.

What trials upstream await you,

Hearkening Nature’s call?

You splash and crash over gravel and rock,

Straining to reach the falls.

Man’s net catches and thwarts you;

Bears struggle to make of you a meal.

Still upstream you strive, caught in the throes

Of Nature’s relentless peal.

Urgency of regeneration makes you

Oblivious to outside sensation.

Instinct to spawn, twilight or dawn

Propels you forward to your destination.
