Analysis of I cross till I am weary

I cross till I am weary
A Mountain—in my mind—
More Mountains—then a Sea—
More Seas—And then
A Desert—find—

And My Horizon blocks
With steady—drifting—Grains
Of unconjectured quantity—
As Asiatic Rains—

Nor this—defeat my Pace—
It hinder from the West
But as an Enemy's Salute
One hurrying to Rest—

What merit had the Goal—
Except there intervene
Faint Doubt—and far Competitor—
To jeopardize the Gain?

At last—the Grace in sight—
I shout unto my feet—
I offer them the Whole of Heaven
The instant that we meet—

They strive—and yet delay—
They perish—Do we die—
Or is this Death's Experiment—
Reversed—in Victory?
