Analysis of The Past

I fling the past behind me, like a robe
Worn threadbare at the seams, and out of date.
I have outgrown it. Wherefore should I weep
And dwell upon its beauty, and its dyes
Of oriental splendor, or complain
That I must needs discard it? I can weave
Upon the shuttles of the future years
A fabric far more durable. Subdued,
It may be, in the blending of its hues,
Where somber shades commingle, yet the gleam
Of golden warp shall shoot it through and through,
While over all a fadeless luster lies,
And starred with gems made out of crystalled tears,
My new robe shall be richer than the old.
