Forever?

What is "Forever"? Is it illusion, hope or unfathomable.

FOREVER

Forever is infinity,
A number far away,
A thought, or dream, just out of reach,
Of life, of night or day.

Forever is untouchable,
To hand, or mind, or eye,
It winds the world a million times,
And touches both earth and sky.

Forever is the moments,
That blend the day and night,
That put your heart into a trance,
That awakens not with pure might.

For forever is unbearable,
After it has lain in the light,
It stands, to us, an open door,
Reached only by taking flight.

But forever patiently lies in wait,
Standing tauntingly ajar,
Daring all who chance to see,
To catch it from afar.

Forever is invisible,
To all but a fleeting glance,
That passes when hearts are overcome,
By an even deeper trance.

Forever is far, far down the road,
Far past where my feet shall stall,
Far in the eye that none can forebode,
And far after the final fall.

Forever is unreachable,
By hand, or mind, or light,
To anything in knowledge of man besides,
That moment of eternal night.
