Shifting Horizons

Ever evolving
We change with the tides
That move us
inexorably
Onward
To a destination
Only dimly seen
On the horizon.
Yet as we gaze
Ahead into the unknown
The shifting mists
Obscure the vision
Until that which we thought
Would be is now
No longer there.
It has been replaced
By something
Unimagined
And yet unfulfilled
But drawing
Us into itself.
