Classic Poem

I know it must be winter (though I sleep) --
I know it must be winter, for I dream
I dip my bare feet in the running stream,
And flowers are many, and the grass grows deep.

I know I must be old (how age deceives!)
I know I must be old, for, all unseen,
My heart grows young, as autumn fields grow green,
When late rains patter on the falling sheaves.

I know I must be tired (and tired souls err) --
I know I must be tired, for all my soul
To deeds of daring beats a glad, faint roll,
As storms the riven pine to music stir.

I know I must be dying (Death draws near) --
I know I must be dying, for I crave
Life -- life, strong life, and think not of the grave,
And turf-bound silence, in the frosty year.
